The only reason for sb_getblk() failing is if it can't allocate
the buffer_head. So return ENOMEM instead when it fails.

The only reason for sb_getblk() failing is if it can't allocate
the buffer_head. So return ENOMEM instead when it fails.

* [Ocfs2-devel] [PATCH 1/2] ocfs2: return ENOMEM while sb_getblk failing

The only reason for sb_getblk() failing is if it can't allocate
the buffer_head. So return ENOMEM instead when it fails.
