Subject: [PATCH] vfs: atomic f_pos access in llseek()
Date: Sun, 16 Mar 2014 14:24:08 -0500 [thread overview]
Message-ID: <1394997848-11360-1-git-send-email-ebiggers3@gmail.com> (raw)
Commit 9c225f2655e36a4 ("vfs: atomic f_pos accesses as per POSIX") changed
several system calls to use fdget_pos() instead of fdget(), but missed
sys_llseek(). Fix it.
