Preparation for further changes. It touches few functions in fatent.c and prevents them from marking the superblock as dirty unnecessarily often. Namely, instead of marking it as dirty in the internal tight loops - do it only once at the end of the functions. And instead of marking it as dirty while holding the FAT table lock, do it outside the lock. The reason for this patch is that marking the superblock as dirty will soon become a little bit heavier operation, so it is cleaner to do this only when it is necessary. Signed-off-by:

A preparation patch which introduces a 'mark_fsinfo_dirty()' helper function which just sets the 's_dirt' flag to 1 so far. I'll add more code to this helper later, so I do not mark it as 'inline'. Signed-off-by:

This is patchset makes fatfs stop using the VFS '->write_super()' method for writing out the FSINFO block. The final goal is to get rid of the 'sync_supers()' kernel thread. This kernel thread wakes up every 5 seconds (by default) and calls '->write_super()' for all mounted file-systems. And the bad thing is that this is done even if all the superblocks are clean. Moreover, some file-systems do not even need this end they do not register the '->write_super()' method at all (e.g., btrfs). So 'sync_supers()' most often just generates useless wake-ups and wastes power. I am trying to make all file-systems independent of '->write_super()' and plan to remove 'sync_supers()' and '->write_super' completely once there are no more users. The '->write_supers()' method is mostly used by baroque file-systems like hfs, udf, etc. Modern file-systems like btrfs and xfs do not use it. This justifies removing this stuff from VFS completely and make every FS self-manage own superblock. Tested with xfstests. This patch: Preparation for further changes. It introduces a special inode ('fsinfo_inode') in FAT file-system which we'll later use for managing the FSINFO block. Note, this there is already one special inode ('fat_inode') which is used for managing the FAT tables. Introduce new 'MSDOS_FSINFO_INO' constant for this special inode. It is safe to do because FAT file-system does not store inode numbers on the media but generates them run-time. I've also cleaned up the comment to existing 'MSDOS_ROOT_INO' constant, while on it.

There are two cases that the cache flush is needed to avoid data loss against unexpected hang or power failure. One is sync file function (i.e. nilfs_sync_file) and another is checkpointing ioctl. This issues a cache flush request to device for such cases if barrier mount option is enabled, and makes sure data really is on persistent storage on their completion. Signed-off-by:

Will Deacon authored
As described in commit 07d106d0 ("vfs: fix up ENOIOCTLCMD error handling"), drivers should return -ENOIOCTLCMD if they receive an ioctl command which they don't understand. Doing so will result in -ENOTTY being returned to userspace, which matches the behaviour of the compat layer if it fails to translate an ioctl command. This patch fixes the pipe ioctl to return -ENOIOCTLCMD instead of -EINVAL when passed an unknown ioctl command. Signed-off-by:

The init/mount.o source files produce a number of sparse warnings of the type: warning: incorrect type in argument 1 (different address spaces) expected char [noderef] <asn:1>*dev_name got char *name This is due to the syscalls expecting some of the arguments to be user pointers but they are being passed as kernel pointers. This is harmless but adds a lot of noise to a sparse build. To limit the noise just disable the sparse checking in the relevant source files, but still display a warning so that the user knows this has been done. Since the sparse checking has been disabled we can also remove the __user __force casts that are scattered thru the source. Signed-off-by:

Previous code was using optimizations which were developed to work well even on narrow-word CPUs (by today's standards). But Linux runs only on 32-bit and wider CPUs. We can use that. First: using 32x32->64 multiply and trivial 32-bit shift, we can correctly divide by 10 much larger numbers, and thus we can print groups of 9 digits instead of groups of 5 digits. Next: there are two algorithms to print larger numbers. One is generic: divide by 1000000000 and repeatedly print groups of (up to) 9 digits. It's conceptually simple, but requires an (unsigned long long) / 1000000000 division. Second algorithm splits 64-bit unsigned long long into 16-bit chunks, manipulates them cleverly and generates groups of 4 decimal digits. It so happens that it does NOT require long long division. If long is > 32 bits, division of 64-bit values is relatively easy, and we will use the first algorithm. If long long is > 64 bits (strange architecture with VERY large long long), second algorithm can't be used, and we again use the first one. Else (if long is 32 bits and long long is 64 bits) we use second one. And third: there is a simple optimization which takes fast path not only for zero as was done before, but for all one-digit numbers. In all tested cases new code is faster than old one, in many cases by 30%, in few cases by more than 50% (for example, on x86-32, conversion of 12345678). Code growth is ~0 in 32-bit case and ~130 bytes in 64-bit case. This patch is based upon an original from Michal Nazarewicz. [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by:

Grant Likely authored
The '%p' output of the kernel's vsprintf() uses spec.field_width to determine how many digits to output based on 2 * sizeof(void*) so that all digits of a pointer are shown. ie. a pointer will be output as "001A2B3C" instead of "1A2B3C". However, if the '#' flag is used in the format (%#p), then the code doesn't take into account the width of the '0x' prefix and will end up outputing "0x1A2B3C" instead of "0x001A2B3C". This patch reworks the "pointer()" format hook to include 2 characters for the '0x' prefix if the '#' flag is included. [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by:

ULONG_MAX is often used to check for integer overflow when calculating allocation size. While ULONG_MAX happens to work on most systems, there is no guarantee that `size_t' must be the same size as `long'. This patch introduces SIZE_MAX, the maximum value of `size_t', to improve portability and readability for allocation size validation. Signed-off-by:

If the rtc reports the time might be invalid due to oscillator failure, M41T93_FLAG_OF flag must not be reset by get_time() as the read operation doesn't make the time valid. Without this patch, only the first get_time() reported an invalid time, the second get_time() reported a valid time althought the reported time is probably wrong due to oscillator failure. Instead of resetting in get_time(), with this patch M41T93_FLAG_OF is reset in set_time() when a valid time is to be written. Signed-off-by:

Using %ps in a printk format will sometimes fail silently and print the empty string if the address passed in does not match a symbol that kallsyms knows about. But using %pS will fall back to printing the full address if kallsyms can't find the symbol. Make %ps act the same as %pS by falling back to printing the address. While we're here also make %ps print the module that a symbol comes from so that it matches what %pS already does. Take this simple function for example (in a module): static void test_printk(void) { int test; pr_info("with pS: %pS\n", &test); pr_info("with ps: %ps\n", &test); } Before this patch: with pS: 0xdff7df44 with ps: After this patch: with pS: 0xdff7df44 with ps: 0xdff7df44 Signed-off-by:
