[PATCH] ufs: not usual amounts of fragments per block
The writing to UFS file system with block/fragment!=8 may cause bogus behaviour. The problem in "ufs_bitmap_search" function, which doesn't work correctly in "block/fragment!=8" case. The idea is stolen from BSD code. Signed-off-by: Evgeniy Dushistov <dushistov@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
