Documentation: filesystems: convert vfat.txt to RST

2020-01-10T17:58:45+00:00

Converts vfat.txt to the reStructuredText format, improving presentation without changing the underlying content. Signed-off-by: Daniel W. S. Almeida ----------------------------------------------------------- Changes in v3: Removed unnecessary markup. Removed section "BUG REPORTS" as recommended by the maintainer. Changes in v2: Refactored long lines as pointed out by Jonathan Copied the maintainer Updated the reference in the MAINTAINERS file for vfat I did not move this into admin-guide, waiting on what the maintainer has to say about this and also about old sections in the text, if any.

Documentation/filesystems/vfat.txt: fix a remark that implies UCS2

2017-12-21T20:39:28+00:00

All non-historic operating systems support the full range of Unicode here, thus you can make filenames for example in Gothic (𐌼𐌴𐍉𐍅), the other Gothic (𝓂ℯℴ𝓌) or the third Gothic (𝗆𝖾𝗈𝗐), or declare something as 💩. Characters above U+FFFF are encoded on four bytes. Signed-off-by: Adam Borowski Acked-by: OGAWA Hirofumi Signed-off-by: Jonathan Corbet

fat: add config option to set UTF-8 mount option by default

2016-03-22T22:36:02+00:00

FAT has long supported its own default file name encoding config setting, separate from CONFIG_NLS_DEFAULT. However, if UTF-8 encoded file names are desired FAT character set should not be set to utf8 since this would make file names case sensitive even if case insensitive matching is requested. Instead, "utf8" mount options should be provided to enable UTF-8 file names in FAT file system. Unfortunately, there was no possibility to set the default value of this option so on UTF-8 system "utf8" mount option had to be added manually to most FAT mounts. This patch adds config option to set such default value. Signed-off-by: Maciej S. Szmigiero Acked-by: OGAWA Hirofumi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

fs/fat/: add support for DOS 1.x formatted volumes

2014-06-06T23:08:10+00:00

Add structure for parsed BPB information, struct fat_bios_param_block, and move all of the deserialization and validation logic from fat_fill_super() into fat_read_bpb(). Add a 'dos1xfloppy' mount option to infer DOS 2.x BIOS Parameter Block defaults from block device geometry for ancient floppies and floppy images, as a fall-back from the default BPB parsing logic. When fat_read_bpb() finds an invalid FAT filesystem and dos1xfloppy is set, fall back to fat_read_static_bpb(). fat_read_static_bpb() validates that the entire BPB is zero, and that the floppy has a DOS-style 8086 code bootstrapping header. Then it fills in default BPB values from media size and a table.[0] Media size is assumed to be static for archaic FAT volumes. See also: [1]. Fixes kernel.org bug #42617.

fat: provide option for setting timezone offset

2012-12-18T01:15:22+00:00

So far FAT either offsets time stamps by sys_tz.minuteswest or leaves them as they are (when tz=UTC mount option is used). However in some cases it is useful if one can specify time stamp offset on his own (e.g. when time zone of the camera connected is different from time zone of the computer, or when HW clock is in UTC and thus sys_tz.minuteswest == 0). So provide a mount option time_offset= which allows user to specify offset in minutes that should be applied to time stamps on the filesystem. akpm: this code would work incorrectly when used via `mount -o remount', because cached inodes would not be updated. But fatfs's fat_remount() is basically a no-op anyway. Signed-off-by: Jan Kara Acked-by: OGAWA Hirofumi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
