    Subject[PATCH 3.16 275/357] fs/notify: dont show f_handle if exportfs_encode_inode_fh failed
    Date
    3.16-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Andrey Vagin <avagin@openvz.org>

    commit 7e8824816bda16bb11ff5ff1e1212d642e57b0b3 upstream.

    Currently we handle only ENOSPC. In case of other errors the file_handle
    variable isn't filled properly and we will show a part of stack.
