From 6c474f7bc1ef70bc05ce486e7e7e524124122de8 Mon Sep 17 00:00:00 2001 From: Maxim Date: Mon, 14 Mar 2011 13:19:21 +0000 Subject: [PATCH] GFS2: Adding missing unlock_page() gfs2_write_begin() calls grab_cache_page_write_begin() that returns *locked* page. Correspondent error-handling path lacks for unlock_page() call: > out: > if (error == 0) > return 0; > > page_cache_release(page); The whole system hangs if gfs2_unstuff_dinode() called from gfs2_write_begin() failed for some reason.
