From: David Jeffery Date: Tue, 5 Aug 2014 15:19:42 +0000 (-0400) Subject: nfs: Don't busy-wait on SIGKILL in __nfs_iocounter_wait X-Git-Tag: omap-for-v3.17/fixes-against-rc2~12^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=92a56555bd576c61b27a5cab9f38a33a1e9a1df5;p=pandora-kernel.git nfs: Don't busy-wait on SIGKILL in __nfs_iocounter_wait If a SIGKILL is sent to a task waiting in __nfs_iocounter_wait, it will busy-wait or soft lockup in its while loop. nfs_wait_bit_killable won't sleep, and the loop won't exit on the error return. Stop the busy-wait by breaking out of the loop when nfs_wait_bit_killable returns an error. Signed-off-by: David Jeffery Signed-off-by: Trond Myklebust --- Reading git-diff-tree failed
