Subject: [PATCH] NFS: Cleanup if nfs_match_client is interrupted
Date: Tue, 11 Jun 2019 12:57:52 -0400 [thread overview]
Message-ID: <65b675cec79d140df64bc30def88b1def32bf87e.1560272160.git.bcodding@redhat.com> (raw)
Don't bail out before cleaning up a new allocation if the wait for
searching for a matching nfs client is interrupted. Memory leaks.
Reported-by: syzbot+7fe11b49c1cc30e3fce2@syzkaller.appspotmail.com
Fixes: 950a578c6128 ("NFS: make nfs_match_client killable")
