fat (exportfs): fix dentry reconnection

2012-10-05T18:05:09+00:00

Maintain an index of directory inodes by starting cluster, so that
fat_get_parent() can return the proper cached inode rather than inventing
one that cannot be traced back to the filesystem root.

Add a new msdos/vfat binary mount option "nfs" so that FAT filesystems
that are _not_ exported via NFS are not saddled with maintenance of an
index they will never use.

Finally, simplify NFS file handle generation and lookups.  An
ext2-congruent implementation is adequate for FAT needs.

fat: refactor shortname parsing

2012-07-31T00:25:20+00:00

Nearly identical shortname parsing is performed in fat_search_long() and
__fat_readdir().  Extract this code into a function that may be called by
both.

fat: use fat_msg_ratelimit() in fat__get_entry()

2012-06-01T00:49:28+00:00

If an application tries to lookup (opendir/readdir/stat) 5000 files on a
fatfs USB device and the device is unplugged, many message occur, shown
below.  This makes the application slow.  So use the new
fat_msg_ratelimit() decrease the messaging rate.
