fat: fix incorrect function comment

2012-12-21T01:40:20+00:00

fat_search_long() returns 0 on success, -ENOENT/ENOMEM on failure.
Change the function comment accordingly.

While at it, fix some trivial typos.

fs/fat: strip "cp" prefix from codepage in display

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

Option parsing code expects an unsigned integer for the codepage option,
but prefixes and stores this option with "cp" before passing to
load_nls().  This makes the displayed option in /proc an invalid one.
Strip the prefix when printing so that the displayed option is valid for
reuse.

fat: ix mount option parsing

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

parse_options() is supposed to return value < 0 on error however we
returned 0 (success) in a lot of cases.  This actually was not a problem
in practice because match_token() used by parse_options() is clever and
catches most of the problems for us.

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.

Change fatfs so that a warning is emitted when an attempt is made to mount
a filesystem with the unsupported `discard' option.

fat: no need to reset EOF in ent_put for FAT32

2012-10-05T18:05:12+00:00

#define FAT_ENT_EOF(EOF_FAT32)

there is no need to reset value of 'new' for FAT32 as the values is
already correct
