* filter: optimize sk_run_filterEric Dumazet2010-11-191-8/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove pc variable to avoid arithmetic to compute fentry at each filter instruction. Jumps directly manipulate fentry pointer. As the last instruction of filter[] is guaranteed to be a RETURN, and all jumps are before the last instruction, we dont need to check filter bounds (number of instructions in filter array) at each iteration, so we remove it from sk_run_filter() params. On x86_32 remove f_k var introduced in commit 57fe93b374a6b871 (filter: make sure filters dont read uninitialized memory) Note : We could use a CONFIG_ARCH_HAS_{FEW|MANY}_REGISTERS in order to avoid too many ifdefs in this code. This helps compiler to use cpu registers to hold fentry and A accumulator. On x86_32, this saves 401 bytes, and more important, sk_run_filter() runs much faster because less register pressure (One less conditional branch per BPF instruction) # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 2948 0 0 2948 b84 net/core/filter.o 3349 0 0 3349 d15 net/core/filter_pre.o on x86_64 : # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 5173 0 0 5173 1435 net/core/filter.o 5224 0 0 5224 1468 net/core/filter_pre.o Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: David S.

* | i4l: kill big kernel lockArnd Bergmann2010-09-161-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The isdn4linux driver uses the big kernel lock only to serialize access to a few fields in its own modem_info structure. The easiest replacement is a driver-wide mutex. More fine-grained locking would be more appropriate here, but likely harder to implement.

* isdn: autoconvert trivial BKL users to private mutexArnd Bergmann2010-07-131-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Karsten Keil <isdn@linux-pingi.de> Cc: netdev@vger.kernel.org Signed-off-by: David S.

* isdn: avoid calling tty_ldisc_flush() in atomic contextTilman Schmidt2010-07-061-6/+0Star
| | | | | | | | | | | | | | Remove the call to tty_ldisc_flush() from the RESULT_NO_CARRIER branch of isdn_tty_modem_result(), as already proposed in commit 00409bb045887ec5e7b9e351bc080c38ab6bfd33. This avoids a "sleeping function called from invalid context" BUG when the hardware driver calls the statcallb() callback with command==ISDN_STAT_DHUP in atomic context, which in turn calls isdn_tty_modem_result(RESULT_NO_CARRIER, ~), and from there, tty_ldisc_flush() which may sleep.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-306-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | In preparation for porting to kernel CAPI subsystem, include the Gigaset driver's Kconfig directly from ISDN's instead of I4L's. Impact: Kconfig reorganisation, no functional change Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* isdn: Fix missing ifdef in isdn_pppDaniele Venzano2009-01-261-0/+2
| | | | | | | | | | | | | The following patch fixes a warning caused by a missing ifdef in isdn_ppp.c. A function was defined, but never used if CONFIG_IPPP_FILTER was not defined. The warning was: 'get_filter' defined but not used Patch is against 2.6.28.1 Signed-off-by: Daniele Venzano <venza@brownhat.org> Acked-by: Karsten Keil <kkeil@suse.de> Signed-off-by: David S.

* i4l: do not print a warning when shutting down an i4l ppp interfacePaul Bolle2009-01-141-1/+3
| | | | | | | | | | | | | | | When an i4l ppp interface is shut down (e.g. with /sbin/ifdown ippp0) a scary warning is logged: isdn_free_channel: called with invalid drv(-1) or channel(-1) This warning is caused by isdn_net_unbind_channel(), which always calls isdn_free_channel() even if isdn_net_local->isdn_device and isdn_net_local->isdn_channel are (still) in a perfectly acceptable default state, so let's not do that.

| | | | | | | | | | | | | | | | | | | | | | | | | | They would have been better named as get_be16, put_be16, etc. as they were hiding an endian shift inside. They don't add much over explicitly coding the byteshifting and gcc sometimes has a problem with builtin_constant_p inside inline functions, so it may do a better job of byteswapping at compile time rather than runtime.
