From 770908db2adb9dcfa2dabf739ac4d59be7f91ddc Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Tue, 14 Apr 2009 19:48:39 +0200 Subject: ocfs2: fix i_mutex locking in ocfs2_splice_to_file() commit 328eaaba4e41a04c1dc4679d65bea3fee4349d86 upstream. Rearrange locking of i_mutex on destination and call to ocfs2_rw_lock() so locks are only held while buffers are copied with the pipe_to_file() actor, and not while waiting for more data on the pipe.
