Subject: [PATCH] hfsplus: rework processing of return value of bio_alloc() in hfsplus_submit_bio()
Date: Wed, 28 Nov 2012 13:27:34 +0400 [thread overview]
Message-ID: <1354094854.2122.44.camel@slavad-ubuntu> (raw)
Hi,
This patch adds logic of checking return value of bio_alloc() in hfsplus_submit_bio(). In the case of NULL the hfsplus_submit_bio() returns -EIO.
With the best regards,
Vyacheslav Dubeyko.
