From 2ad8ee713566671875216ebcec64f2eda47bd19d Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 8 May 2007 00:12:58 +0100 Subject: [JFFS2] Fix potential memory leak of dead xattrs on unmount. An xattr_datum which ends up orphaned should be freed by the GC thread. But if we umount before the GC thread is finished, or if we mount read-only and the GC thread never runs, they might never be freed. Clean them up during unmount, if there are any left.
