Remove initialization of vaiable in caller of memory cgroup function. Actually, it's return value of memcg function but it's initialized in caller. Some memory cgroup uses following style to bring the result of start function to the end function for avoiding races. mem_cgroup_start_A(&(*ptr)) /* Something very complicated can happen here. */ mem_cgroup_end_A(*ptr) In some calls, *ptr should be initialized to NULL be caller. But it's ugly. This patch fixes that *ptr is initialized by _start function. Signed-off-by:

minix bit operations are only used by minix filesystem and useless by other modules. Because byte order of inode and block bitmaps is different on each architecture like below: m68k: big-endian 16bit indexed bitmaps h8300, microblaze, s390, sparc, m68knommu: big-endian 32 or 64bit indexed bitmaps m32r, mips, sh, xtensa: big-endian 32 or 64bit indexed bitmaps for big-endian mode little-endian bitmaps for little-endian mode Others: little-endian bitmaps In order to move minix bit operations from asm/bitops.h to architecture independent code in minix filesystem, this provides two config options. CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k. CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu, m32r, mips, sh, xtensa). The architectures which always use little-endian bitmaps do not select these options. Finally, we can remove minix bit operations from asm/bitops.h for all architectures. Signed-off-by:

This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic implementation of find_*_bit_le() in lib/find_next_bit.c or not. For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which enable CONFIG_GENERIC_FIND_NEXT_BIT. But m68knommu wants to define own faster find_next_zero_bit_le() and continues using generic find_next_{,zero_}bit(). (CONFIG_GENERIC_FIND_NEXT_BIT and !CONFIG_GENERIC_FIND_BIT_LE) Signed-off-by: -

Akinobu Mita authored
This makes the little-endian bitops take any pointer types by changing the prototypes and adding casts in the preprocessor macros. That would seem to at least make all the filesystem code happier, and they can continue to do just something like #define ext2_set_bit __test_and_set_bit_le (or whatever the exact sequence ends up being).

This patch series introduces little-endian bit operations in asm/bitops.h for all architectures and converts all ext2 non-atomic and minix bit operations to use little-endian bit operations. It enables us to remove ext2 non-atomic and minix bit operations from asm/bitops.h. The reason they should be removed from asm/bitops.h is as follows: For ext2 non-atomic bit operations, they are used for little-endian byte order bitmap access by some filesystems and modules. But using ext2_*() functions on a module other than ext2 filesystem makes some feel strange. For minix bit operations, they are only used by minix filesystem and are useless by other modules. Because byte order of inode and block bitmap is This patch: In order to make the forthcoming changes smaller, this merges macro definisions in asm-generic/bitops/le.h for big-endian and little-endian as much as possible. This also removes unused BITOP_WORD macro. Signed-off-by:

asm-generic/bitops/le.h is only intended to be included directly from asm-generic/bitops/ext2-non-atomic.h or asm-generic/bitops/minix-le.h which implements generic ext2 or minix bit operations. This stops including asm-generic/bitops/le.h directly and use ext2 non-atomic bit operations instead. It seems odd to use ext2_*_bit() on rds, but it will replaced with __{set,clear,test}_bit_le() after introducing little endian bit operations for all architectures. This indirect step is necessary to maintain bisectability for some architectures which have their own little-endian bit operations. Signed-off-by: -

This reverts commit a7a75c8f. There are two different variations on how Intel hardware addresses the "Hardware Status Page". One as a location in physical memory and the other as an offset into the virtual memory of the GPU, used in more recent chipsets. (The HWS itself is a cacheable region of memory which the GPU can write to without requiring CPU synchronisation, used for updating various details of hardware state, such as the position of the GPU head in the ringbuffer, the last breadcrumb seqno, etc). These two types of addresses were updated in different locations of code - one inline with the ringbuffer initialisation, and the other during device initialisation. (The HWS page is logically associated with the rings, and there is one HWS page per ring.) During resume, only the ringbuffers were being re-initialised along with the virtual HWS page, leaving the older physical address HWS untouched. This then caused a hang on the older gen3/4 (915GM, 945GM, 965GM) the first time we tried to synchronise the GPU as the breadcrumbs were never being updated. Reported-and-tested-by:

A conflict between 52c50567 ("mm: swap: unlock swapfile inode mutex before closing file on bad swapfiles") and 83ef99be ("sys_swapon: remove did_down variable") caused a double unlock of the inode mutex (once in bad_swap: before the filp_close, once at the end just before returning). The patch which added the extra unlock cleared did_down to avoid unlocking twice, but the other patch removed the did_down variable. To fix, set inode to NULL after the first unlock, since it will be used after that point only for the final unlock. While checking this patch, I found a path which could unlock without locking, in case the same inode was added as a swapfile twice. To fix, move the setting of the inode variable further down, to just before claim_swapfile, which will lock the inode before doing anything else.

Instead of always creating a huge (268K) deflate_workspace with the maximum compression parameters (windowBits=15, memLevel=8), allow the caller to obtain a smaller workspace by specifying smaller parameter values. For example, when capturing oops and panic reports to a medium with limited capacity, such as NVRAM, compression may be the only way to capture the whole report. In this case, a small workspace (24K works fine) is a win, whether you allocate the workspace when you need it (i.e., during an oops or panic) or at boot time. I've verified that this patch works with all accepted values of windowBits (positive and negative), memLevel, and compression level. Signed-off-by:
