[PATCH] ufs: truncate should allocate block for last byte
This patch fixes buggy behaviour of UFS in such kind of scenario: open(, O_TRUNC...) ftruncate(, 1024) ftruncate(, 0) Such a scenario causes ufs_panic and remount read-only. This happen because of according to specification UFS should always allocate block for last byte, and many parts of our implementation rely on this, but `ufs_truncate' doesn't care about this. To make possible return error code and to know about old size, this patch removes `truncate' from ufs inode_operations and uses `setattr' method to call ufs_truncate.
