* UBIFS: make ubifs_ro_mode() not inlineAdrian Hunter2008-08-133-14/+15
| | | | | | | | | | | We use ubifs_ro_mode() quite a lot, and not in fast-path, so there is no reason to blow the code up by having it inlined. Also, we usually want R/O mode change to be seen to other CPUs as soon as possible, so when we make this a function call, we will automatically have a memory barrier.

* UBIFS: ensure UBIFS switches to read-only on errorAdrian Hunter2008-08-131-0/+2
| | | | | | | | | | | | UBI transparently handles write errors by automatically copying and remapping the affected eraseblock. If UBI is unable to do that, for example its pool of eraseblocks reserved for bad block handling is empty, then the error is propagated to UBIFS. UBIFS must protect the media from falling into an inconsistent state by immediately switching to read-only mode. In the case of log updates, this was not being done.

* UBIFS: fix error return in failure modeAdrian Hunter2008-08-131-3/+4
| | | | | | | | | UBIFS recovery testing debug facility simulates media failures. When simulating an IO error, the error code returned must be -EIO but it was not always if the user switched off the debug recovery testing option at the same time.

* UBIFS: free budget in delete_inode as wellArtem Bityutskiy2008-08-131-3/+5
| | | | | | | | Although the inode is marked as clean when it is being deleted, it might stay and be used as orphan, and be marked as dirty. So we have to free the budget when we delete it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBIFS: fix budgeting calculationsArtem Bityutskiy2008-08-132-4/+4
| | | | | | | | | | | | | | The 'ubifs_release_dirty_inode_budget()' was buggy and incorrectly freed the budget, which led to not freeing all dirty data budget. This patch fixes that. Also, this patch fixes ubifs_mkdir() which passed 1 in dirty_ino_d, which makes no sense. Well, it is harmless though. Also, add few more useful assertions. And improve few debugging messages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are users that are running UDP applications that require a large receive queue size in order to get good performance. To prevent allocation failures for rx_rings when using non-SRQ mode and large recv_queue_size (1K or larger), use vmalloc() instead of kcalloc() to alocate rx_rings.

| * | | IB/ehca: Discard double CQE for one WRAlexander Schmidt2008-08-124-20/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under rare circumstances, the ehca hardware might erroneously generate two CQEs for the same WQE, which is not compliant to the IB spec and will cause unpredictable errors like memory being freed twice. To avoid this problem, the driver needs to detect the second CQE and discard it. For this purpose, introduce an array holding as many elements as the SQ of the QP, called sq_map. Each sq_map entry stores a "reported" flag for one WQE in the SQ. When a work request is posted to the SQ, the respective "reported" flag is set to zero. After the arrival of a CQE, the flag is set to 1, which allows to detect the occurence of a second CQE. The mapping between WQE / CQE and the corresponding sq_map element is implemented by replacing the lowest 16 Bits of the wr_id with the index in the queue map. The original 16 Bits are stored in the sq_map entry and are restored when the CQE is passed to the application.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idr_find() function may fail when trying to get the QP that is associated with a CQE, e.g. when a QP has been destroyed between the generation of a CQE and the poll request for it. In consequence, the return value of idr_find() must be checked and the CQE must be discarded when the QP cannot be found.

| * | | IB/ehca: Update qp_state on cached modify_qp()Alexander Schmidt2008-08-121-4/+10
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the introduction of the port auto-detect mode for ehca, calls to modify_qp() may be cached in the device driver when the ports are not activated yet. When a modify_qp() call is cached, the qp state remains untouched until the port is activated, which will leave the qp in the reset state. In the reset state, however, it is not allowed to post SQ WQEs, which confuses applications like ib_mad. The solution for this problem is to immediately set the qp state as requested by modify_qp(), even when the call is cached.

This mapping is not enabled until the architecture specific cpu_init() function is run, which causes problems since some generic code is run before this point. In particular when CONFIG_PRINTK_TIME is enabled, the boot cpu will trap on the access to per-cpu memory at the first printk() call so the boot will fail without the kernel printing anything to the console. Fix this by allocating percpu memory for cpu0 in the kernel data section and doing all initialization to enable percpu access in head.S before calling any generic code. Other cpus must take care not to access per-cpu variables too early, but their code path from start_secondary() to cpu_init() is all in arch/ia64 Signed-off-by: Tony Luck <tony.luck@intel.com>

This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds).

* | | | seq_file: add seq_cpumask(), seq_nodemask()Alexey Dobriyan2008-08-134-0/+38

This became noticed with NR_CPUS=4096 patches, when length of printed representation of cpumask becase 1152, but cat(1) continued to read with 1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns 1023, check returns -EINVAL. Fix it by switching to seq_file, so handler will just fill buffer and doesn't care about offsets, length, filling EOF and all this crap. For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and seq_nodemask().
