Subject: [PATCH 1/2] xfs: tracepoints for xfs_iunlink() and xfs_iunlink_remove()
Date: Thu, 25 Apr 2013 11:41:29 -0400 [thread overview]
Message-ID: <1366904490-46821-2-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1366904490-46821-1-git-send-email-bfoster@redhat.com>
Add tracepoints for xfs_iunlink() and xfs_iunlink_remove(). These
tracepoints are useful for debugging inode link (and unlinked list
issues).
