Message-ID: <alpine.LNX.2.00.1605241636220.31937@cbobk.fhfr.pm> Date: Tue, 24 May 2016 16:38:34 +0200 (CEST) From: Jiri Kosina <jikos@...nel.org> To: Jens Axboe <axboe@...nel.dk> cc: Kent Overstreet <kent.overstreet@...il.com>, Eric Wheeler <bcache@...ts.ewheeler.net>, linux-bcache@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 3/4] bcache: bch_gc_thread() is not freezable From: Jiri Kosina <jkosina@...e.cz> bch_gc_thread() doesn't mark itself freezable, so calling try_to_freeze() in its context is just an expensive no-op.
