  This is a new version of my patches to address a rare problem with nfsd
closing files faster than __fput() can complete the close in a different
thread.

This time I'm simply switching to __fput_sync().  I cannot see any
reason that this would be a problem, but if any else does and can show
me what I'm missing, I'd appreciate it.

Thanks,
NeilBrown


 [PATCH 1/3] nfsd: use __fput_sync() to avoid delayed closing of
 [PATCH 2/3] nfsd: Don't leave work of closing files to a work queue.
 [PATCH 3/3] VFS: don't export flush_delayed_fput().

Looks good to me.

Much better than the previous attempts, imho.
