From 80e96c5484be788f277eead9cabf88cf8e430419 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Fri, 7 Nov 2014 15:09:46 -0500 Subject: [PATCH] dm thin: do not allow thin device activation while pool is suspended Otherwise IO could be issued to the pool while it is suspended. Care was taken to properly interlock between the thin and thin-pool targets when accessing the pool's 'suspended' flag. The thin_ctr will not add a new thin device to the pool's active_thins list if the pool is susepended. Signed-off-by: Mike Snitzer Acked-by: Joe Thornber --- Reading git-format-patch failed
