Mikulas Patocka 35a9af8ddb dm: use noio when sending kobject event ... commit 6958c1c640 upstream. kobject_uevent may allocate memory and it may be called while there are dm devices suspended. The allocation may recurse into a suspended device, causing a deadlock. We must set the noio flag when sending a uevent. The observed deadlock was reported here: https://www.redhat.com/archives/dm-devel/2020-March/msg00025.html Reported-by: Khazhismel Kumykov <khazhy@google.com> Reported-by: Tahsin Erdogan <tahsin@google.com> Reported-by: Gabriel Krisman Bertazi <krisman@collabora.com> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2020-07-16 08:17:27 +02:00
