The fast system-call fall-back-path has a race: it reads PSR, modifies some bits, then writes back the new PSR. Unfortunately, the contents of PSR may change between reading and writing it. For example, an interrupt could occur which could trigger a context-switch. The context-switch might in turn flush the floating-point-high (FPH) partition to memory, clear PSR.MFH, and set PSR.DFH. To prevent this race, the patch below turns off PSR.I before reading PSR. This fixes a floating-point corruption problem that was observed on a system with a libc which has the fast system-call support enabled. The performance impact is minimal (on the order of a handful of cycles). Signed-off-by:

I waffled over this for ages. On balance, I think it's best to mark those bh's as uptodate. And on reflection, I'm not sure why we go bringing ramdisk blockdev pages uptodate all over the place anyway. But ramdisk is weird and it passes testing. Let those dogs sleep. Signed-off-by:

From: Martin Schwidefsky <schwidefsky@de.ibm.com> Cleanup s390* string functions. This replaces the 31/64 bit assembler files (strcmp[64].S, strcpy[64].S & strncpy[64].S) with a single string.c file that uses some inline assemblies to issue the string instructions. In addition some more of the generic string function got an architecture dependent implementation. Signed-off-by:

From: Andy Whitcroft <apw@shadowen.org> Both modprobe_path and hotplug_path are arbitrarily sized at 256 bytes and that size is also expressed directly in the sysctl code. It seems reasonable to define a standard length and use that for consitancy. This patch introduces the constant KMOD_PATH_LEN and uses that. Signed-off-by:

From: Anton Altaparmakov <aia21@cam.ac.uk> A filesystem's ->writepage() implementation nowadays must run either redirty_page_for_writepage() or the combination of set_page_writeback()/ end_page_writeback(). Failure to do so leaves the page itself marked clean but it is tagged as dirty in the radix tree (PAGECACHE_TAG_DIRTY). This incoherency can lead to all sorts of hard-to-debug problems in the filesystem like having dirty inodes at umount and losing written data. The patch updates Documentation/filesystems/Locking to reflect this requirement. Signed-off-by:

struct page_state is large (148 bytes) and we put them on the stack in awkward code paths (page reclaim...) So implement a simple read_page_state() which can be used to pluck out a single member from the all-cpus page_state accumulators. Signed-off-by:

Page reclaim bales out very early if reclaim isn't working out for !__GFP_FS allocation attempts. It was a fairly arbitrary thing in the first place and chances are the caller will simply retry the allocation or will do something which is disruptive to userspace. So remove that code and do much more scanning. Signed-off-by:

Andrew Morton authored
Teach page reclaim to understand synchronous ->writepage implementations. If ->writepage completed I/O prior to returning we can proceed to reclaim the page without giving it another trip around the LRU. This is beneficial for ramdisk-backed S_ISREG files: we can reclaim the file's pages as fast as the ramdisk driver needs to allocate them and this prevents I/O errors due to OOM in rd_blkdev_pagecache_IO().
