* Makes BFS code endianness-clean. * Fixes some signedness warnings. * Fixes a problem in fs/bfs/inode.c:164 where inodes not synced to disk don't get fully marked as clean. Here's how to reproduce it: # mount -o loop -t bfs /bfs.img /mnt # df -i /mnt Filesystem Inodes IUsed IFree IUse% Mounted on /bfs.img 48 1 47 3% /mnt # df -k /mnt Filesystem 1K-blocks Used Available Use% Mounted on /bfs.img 512 5 508 1% /mnt # cp 60k-archive.zip /mnt/mt.zip # df -k /mnt Filesystem 1K-blocks Used Available Use% Mounted on /bfs.img 512 65 447 13% /mnt # df -i /mnt Filesystem Inodes IUsed IFree IUse% Mounted on /bfs.img 48 2 46 5% /mnt # rm /mnt/mt.zip # echo $? 0 [If the unlink happens before the buffers flush, the following happens:] # df -i /mnt Filesystem Inodes IUsed IFree IUse% Mounted on /bfs.img 48 2 46 5% /mnt # df -k /mnt Filesystem 1K-blocks Used Available Use% Mounted on /bfs.img 512 65 447 13% /mnt fs/bfs/bfs.h | 1 Signed-off-by: Andrew Stribblehill <ads@wompom.org> Cc: <tigran@veritas.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
