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.

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.

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.

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.

The test program below will hang because io_getevents() uses add_wait_queue_exclusive(), which means the wake_up() in io_destroy() only wakes up one of the threads. Fix this by using wake_up_all() in the aio code paths where we want to make sure no one gets stuck. // t.c -- compile with gcc -lpthread -laio t.c #include <libaio.h> #include <pthread.h> #include <stdio.h> #include <unistd.h> static const int nthr = 2; void *getev(void *ctx) { struct io_event ev; io_getevents(ctx, 1, 1, &ev, NULL); printf("io_getevents returned\n"); return NULL; } int main(int argc, char *argv[]) { io_context_t ctx = 0; pthread_t thread[nthr]; int i; io_setup(1024, &ctx); for (i = 0; i < nthr; ++i) pthread_create(&thread[i], NULL, getev, ctx); sleep(1); io_destroy(ctx); for (i = 0; i < nthr; ++i) pthread_join(thread[i], NULL); return 0; } Signed-off-by: NRoland Dreier <roland@purestorage.com> Reviewed-by: NJeff Moyer <jmoyer@redhat.com> Cc: <stable@kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

ADFS (FileCore) storage complies with the RISC OS filetype specification (12 bits of file type information is stored in the file load address, rather than using a file extension). The existing driver largely ignores this information and does not present it to the end user. It is desirable that stored filetypes be made visible to the end user to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu) or to a network share which can be accessed by real Acorn systems. This patch implements a per-mount filetype suffix option (use -o ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each file. This type suffix is compatible with that used by RISC OS systems that access network servers using NFS client software and by RPCemu's host filing system.

ADFS (FileCore) storage complies with the RISC OS timestamp specification (40-bit centiseconds since 01 Jan 1900 00:00:00). It is desirable that stored timestamp precision be maintained to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu). This patch implements a full-precision conversion from ADFS to Unix timestamp as the existing driver, for ease of calculation with old 32-bit compilers, uses the common trick of shifting the 40-bits representing centiseconds around into 32-bits representing seconds thereby losing precision.

Kernel crashes in fs/adfs module when accessing directories with a large number of objects on mounted Acorn ADFS E+/F+ format discs (or images) as the existing code writes off the end of the fixed array of struct buffer_head pointers. Additionally, each directory access that didn't crash would leak a buffer as nr_buffers was not adjusted correctly for E+/F+ discs (was always left as one less than required). The patch fixes this by allocating a dynamically-sized set of struct buffer_head pointers if necessary for the E+/F+ case (many directories still do in fact fit in 2048 bytes) and sets the correct nr_buffers so that all buffers are released. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=26072 Tested by tar'ing the contents of my RISC PC's E+ format 20Gb HDD which contains a number of large directories that previously crashed the kernel.
