fat: move fs/vfat/* and fs/msdos/* to fs/fat

2008-11-06T23:41:20Z

This just moves those files, but change link order from MSDOS, VFAT to VFAT, MSDOS. Signed-off-by: OGAWA Hirofumi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

fatfs: add UTC timestamp option

2008-07-25T17:53:34Z

Provide a new mount option ("tz=UTC") for DOS (vfat/msdos) filesystems, allowing timestamps to be in coordinated universal time (UTC) rather than local time in applications where doing this is advantageous. In particular, portable devices that use fat/vfat (such as digital cameras) can benefit from using UTC in their internal clocks, thus avoiding daylight saving time errors and general time ambiguity issues. The user of the device does not have to worry about changing the time when moving from place or when daylight saving changes. The new mount option, when set, disables the counter-adjustment that Linux currently makes to FAT timestamp info in anticipation of the normal userspace time zone correction. When used in this new mode, all daylight saving time and time zone handling is done in userspace as is normal for many other filesystems (like ext3). The default mode, which remains unchanged, is still appropriate when mounting volumes written in Windows (because of its use of local time). I originally based this patch on one submitted last year by Paul Collins, but I updated it to work with current source and changed variable/option naming. Ogawa Hirofumi (who maintains these filesystems) and I discussed this patch at length on lkml, and he suggested using the option name in the attached version of the patch. Barry Bouwsma pointed out a good addition to the patch as well.

Replace BKL with superblock lock in fat/msdos/vfat

2008-06-20T20:05:54Z

This replaces the use of the BKL in the FAT family of filesystems with the existing superblock lock instead. The code already appears to do mostly proper locking with its own private spinlocks (and mutexes), but while the BKL could possibly have been dropped entirely, converting it to use the superblock lock (which is just a regular mutex) is the conservative thing to do. As a per-filesystem mutex, it not only won't have any of the possible latency issues related to the BKL, but the lock is obviously private to the particular filesystem instance and will thus not cause problems for entirely unrelated users like the BKL can.

fat: use __getname()

__getname() is faster than __get_free_page(). Use it. Signed-off-by: OGAWA Hirofumi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

vfat: bug fix for vfat cannot handle filename with 255

2008-04-28T15:58:47Z

This patch fix the problem that the buffer allocated for convert of unicode to utf8 in fat/dir.c is too small. And cannot handle filename with 255 asian characters when mounted with utf8 options. Also it fix the filename length limitation checking in vfat/namei.c that the filename length should be checked against the number of converted unicode characters. Not the length before NLS/UTF8 converted. Signed-off-by: Keith Mok Signed-off-by: OGAWA Hirofumi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mark struct inode_operations const 3

2007-02-12T17:48:46Z

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] fat: add fat_getattr()
