Subject: [PATCH] fs: eventfd - Removed redundant initialization of res in BLOCKing mode
Date: Thu, 19 Apr 2012 20:04:24 +0530 [thread overview]
Message-ID: <1334846064-11994-1-git-send-email-sasikanth.v19@gmail.com> (raw)
Removed redundant initialization of res to 0, since eventfd_write in
blocking mode guarantees res to be either sizeof(ucnt) or -ERESTARTSYS.
