This is a note to let you know that I've just added the patch titled quota: make dquot_quota_sync return errors from ->sync_fs to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: quota-make-dquot_quota_sync-return-errors-from-sync_.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 226e34107b6d98fbdfa9e37c79b9d6c5ca89719a Author: Darrick J. Wong <djwong@xxxxxxxxxx> Date: Sun Jan 30 08:53:16 2022 -0800 quota: make dquot_quota_sync return errors from ->sync_fs [ Upstream commit dd5532a4994bfda0386eb2286ec00758cee08444 ] Strangely, dquot_quota_sync ignores the return code from the ->sync_fs call, which means that quotacalls like Q_SYNC never see the error. This doesn't seem right, so fix that. Signed-off-by: Darrick J.
