Just to chime in: NTFS doesn't need BKL either as it is read-only.

Also it uses its own locking, so once read-write is enabled only a minor
modification will be needed (read mft_ino->i_size under protection of
mftbmp_lock semaphore) to make it race free without the BKL, too. But no
need to worry about that change, I will take care of that later...

Best regards,

Anton
