2010-04-07raw: fsync method is now requiredAnton Blanchard3-1/+4
Commit 148f948ba877f4d3cdef036b1ff6d9f68986706a (vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode) broke the raw driver. We now call through generic_file_aio_write -> generic_write_sync -> vfs_fsync_range. vfs_fsync_range has: if (!fop || !fop->fsync) { ret = -EINVAL; goto out; } But drivers/char/raw.c doesn't set an fsync method. We have two options: fix it or remove the raw driver completely. I'm happy to do either, the fact this has been broken for so long suggests it is rarely used. The patch below adds an fsync method to the raw driver. My knowledge of the block layer is pretty sketchy so this could do with a once over. If we instead decide to remove the raw driver, this patch might still be useful as a backport to 2.6.33 and 2.6.32.

2010-04-07mm: revert "vmscan: get_scan_ratio() cleanup"KOSAKI Motohiro1-14/+9
Shaohua Li reported his tmpfs streaming I/O test can lead to make oom. The test uses a 6G tmpfs in a system with 3G memory. In the tmpfs, there are 6 copies of kernel source and the test does kbuild for each copy. His investigation shows the test has a lot of rotated anon pages and quite few file pages, so get_scan_ratio calculates percent[0] (i.e. scanning percent for anon) to be zero. Actually the percent[0] shoule be a big value, but our calculation round it to zero. Although before commit 84b18490 ("vmscan: get_scan_ratio() cleanup") , we have the same problem too. But the old logic can rescue percent[0]==0 case only when priority==0. It had hided the real issue. I didn't think merely streaming io can makes percent[0]==0 && priority==0 situation. but I was wrong. So, definitely we have to fix such tmpfs streaming io issue. but anyway I revert the regression commit at first. This reverts commit 84b18490d1f1bc7ed5095c929f78bc002eb70f26.

2010-04-07devmem: handle class_create() failureAnton Blanchard1-0/+3
I hit this when we had a bug in IDR for a few days. Basically sysfs would fail to create new inodes since it uses an IDR and therefore class_create would fail.

2010-04-07vesafb: use platform_driver_probe() instead of platform_driver_register()Jan Beulich1-13/+13
Commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b ("platform-drivers: move probe to .devinit.text in drivers/video") introduced a huge amount of section mismatch warnings in vesafb code. Rather than converting all of the annotations, do the obvious and revert the __init -> __devinit change, and use the recommended (in that patch) alternative to calling platform_driver_register(): vesafb depends on information obtained from by kernel at boot time, cannot be a module, and no post-boot devices can ever show up.

When ide taskfile access is being used (for example with hdparm --security commands) and cfq scheduler is selected, the scheduler crashes on BUG in cfq_put_request. The reason is that the cfq scheduler is tracking counts of read and write requests separately; the ide-taskfile subsystem allocates a read request and then flips the flag to make it a write request. The counters in cfq will mismatch. This patch changes ide-taskfile to allocate the READ or WRITE request as required and don't change the flag later.

2010-04-06perf kmem: Fix breakage introduced by 5a0e3ad slab.h scriptArnaldo Carvalho de Melo1-1/+0
Commit 5a0e3ad ("include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h") added a '#include <linux/slab.h>' to tools/perf/builtin-kmem.h because: that tool has lines like this: if (!strcmp(event->name, "kmalloc") || !strcmp(event->name, "kmem_cache_alloc")) { process_alloc_event(data, event, cpu, timestamp, thread, 0); return; } So, using the script regex: >>> import re >>> s = re.compile(r'^(|.*[^a-zA-Z0-9_])_*(slab_is_available|kmem_cache_|k[mzc]alloc|krealloc|kz?free|ksize|__getname|putname)') >>> l = ' !strcmp(event->name, "kmem_cache_alloc")) {' >>> s.search(l) <_sre.SRE_Match object at 0xb77b1ad0> >>> Remove that file that is not available in the tools/perf include path and thus builtin-kmem.c couldn't be compiled.
