From 2d72e7101cc7fff5c1eb21bfcbba51c8002418d2 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 7 Feb 2007 10:25:59 -0500 Subject: [GFS2] Unlock page on prepare_write try lock failure When the try lock of the glock failed in prepare_write we were incorrectly exiting this function with the page still locked. This was resulting in further I/O to this page hanging.
