    [PATCH] PATCH 2/16: NFSD: BKL Removal: Lock export table · 8244559f
    Neil Brown authored
    Change export table lock to (SMP safe) rwsemaphore
    
    As a first step to removing the BKL from nfsd, this patch
    changes the lock used for the export table to be a rwsem semaphore.
    Previously it had the same functionality but depended on the BKL
    for correctness.
    
    As there is no "down_write_interruptible" this patch removes the
    posibility of interrupting the write_lock request, but this should
    never be needed anyway.
