This is a note to let you know that I have just added a patch titled btrfs: cleanup orphans while looking up default subvolume to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt14. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 3202310e882f4cd7ba36785f1f1a0dbb035c3b34 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney <jeffm@suse.com> Date: Fri, 20 Mar 2015 14:02:09 -0400 Subject: btrfs: cleanup orphans while looking up default subvolume commit 727b9784b6085c99c2f836bf4fcc2848dc9cf904 upstream. Orphans in the fs tree are cleaned up via open_ctree and subvolume orphans are cleaned via btrfs_lookup_dentry -- except when a default subvolume is in use. The name for the default subvolume uses a manual lookup that doesn't trigger orphan cleanup and needs to trigger it manually as well. This doesn't apply to the remount case since the subvolumes are cleaned up by walking the root radix tree.
