Bruce Fields\\\\\\" Date: Mon, 9 Jun 2008 16:51:35 -0400 Subject: rpc: minor cleanup of scheduler callback code Try to make the comment here a little more clear and concise. Also, this macro definition seems unnecessary. Signed-off-by: J.

Note that all the NFS operations use their own locking, so don't need the BKL. Ditto for the rpcbind client.
