Subject: [PATCH] hpfs: kstrdup() memory handling
Date: Sat, 21 Mar 2015 12:57:50 -0400 [thread overview]
Message-ID: <1426957070-2914-1-git-send-email-sanidhya.gatech@gmail.com> (raw)
There is a possibility of nothing being allocated to the new_opts in
case of memory pressure, therefore return ENOMEM for such case.
