    [PATCH] Revert UDF inode semaphore locking · 9a45400e
    Peter Osterlund authored
    For some reason I don't understand, the last UDF filesystem update makes
    the UDF deadlock when I write a bunch of mp3 files to a CDRW using the
    packet writing patch.  Both "cp" and pdflush get stuck in __down. 
    
    Reverting the semaphore changes makes the problem go away.  Use the
    kernel lock again, until whatever recursive offender gets fixed.
    
    (The offensive recursion seems to be: write() takes the inode semaphore,
    causes memory pressure, and then trying to write back the inode or dirty
    data to disk tries to get the semaphore again and deadlocks.)
