[PATCH] ext3: ext3_symlink should use GFP_NOFS allocations inside
This patch fixes illegal __GFP_FS allocation inside ext3 transaction in ext3_symlink(). Such allocation may re-enter ext3 code from try_to_free_pages. But JBD/ext3 code keeps a pointer to current journal handle in task_struct and, hence, is not reentrable. This bug led to "Assertion failure in journal_dirty_metadata()" messages. http://bugzilla.openvz.org/show_bug.cgi?id=115 Signed-off-by: Andrey Savochkin <saw@saw.sw.com.sg> Signed-off-by: Kirill Korotaev <dev@openvz.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
