| * [PATCH] Add support for the sys_vmsplice syscallJens Axboe2006-04-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice() moves data to a pipe, with the input being a user address range instead. This uses an approach suggested by Linus, where we can hold partial ranges inside the pages[] map. Hopefully this will be useful for network receive support as well.

* | [PATCH] sky2: reschedule if irq still pendingStephen Hemminger2006-04-261-8/+10
|/ | | | | | | | | | | | This is a workaround for the case edge-triggered irq's. Several users seem to have broken configurations sharing edge-triggered irq's. To avoid losing IRQ's, reshedule if more work arrives. The changes to netdevice.h are to extract the part that puts device back in list into separate inline.

Both of them have drawbacks. This patch kills the scsi layer version after updating the block version with the missing bits: - argument checking - use scatterlist I/O - set number of retries based on the submitted command This is the last user of non-S/G I/O except for the gdth driver, so getting this in ASAP and through the scsi tree would be nie to kill the non-S/G I/O path.

We have a bunch of old bugs for removable storage handling where we probe successfully for a filesystem on the raw disk, but at the same time the kernel recognizes a partition table and creates partition devices. Currently there is no sane way to tell if partitions will show up or not at the time the disk device is announced to userspace. With the delayed events we can simply skip any probe for a filesystem on the raw disk when we find already present partitions.

Call poll requesting POLLERR or POLLPRI (so select/exceptfds works) When poll returns, close the file and go to top of loop. or lseek to start of file and go back to the 'read'. Events are signaled by an object manager calling sysfs_notify(kobj, dir, attr); If the dir is non-NULL, it is used to find a subdirectory which contains the attribute (presumably created by sysfs_create_group). This has a cost of one int per attribute, one wait_queuehead per kobject, one int per open file. The name "sysfs_notify" may be confused with the inotify functionality. Maybe it would be nice to support inotify for sysfs attributes as well?

| * [PATCH] introduce a "kernel-internal pipe object" abstractionIngo Molnar2006-04-102-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | separate out the 'internal pipe object' abstraction, and make it usable to splice. This cleans up and fixes several aspects of the internal splice APIs and the pipe code: - pipes: the allocation and freeing of pipe_inode_info is now more symmetric and more streamlined with existing kernel practices. - splice: small micro-optimization: less pointer dereferencing in splice methods Signed-off-by: Ingo Molnar <mingo@elte.hu> Update XFS for the ->splice_read/->splice_write changes.

* | [PATCH] vesafb: Fix incorrect logo colors in x86_64Antonino A. Daplas2006-04-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS. If both methods are unsupported, change the visual of vesafb to STATIC_PSEUDOCOLOR.

* | [PATCH] knfsd: svcrpc: WARN() instead of returning an error from svc_take_pageJ. Bruce Fields2006-04-111-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every caller of svc_take_page ignores its return value and assumes it succeeded. So just WARN() instead of returning an ignored error. This would have saved some time debugging a recent nfsd4 problem. If there are still failure cases here, then the result is probably that we overwrite an earlier part of the reply while xdr-encoding. While the corrupted reply is a nasty bug, it would be worse to panic here and create the possibility of a remote DOS; hence WARN() instead of BUG(). Signed-off-by: J.

* | [PATCH] module support: record in vermagic ability to unload a modulePaolo 'Blaisorblade' Giarrusso2006-04-111-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An UML user reported (against 2.6.13.3/UML) he got kernel Oopses when trying to rmmod (on a kernel with module unloading enabled) a module compiled with module unloading disabled. As crashing is a very correct thing to do in that case, a solution is altering the vermagic string to include this too. Possibly, however, the code should not crash in this case, even if the module didn't support unloading - it should simply abort the module removal. In this case, fixing that bug would be a better solution. I've not investigated though. (akpm: a bit marginal - root screwed up and shot himself in the foot).
