--- Comment #1 from Pranith Kumar K <pkarampu at redhat.com> ---
    Problem:
    shard_post_lookup_fsync_handler() goes over the list of
    inode-ctx that need to be fsynced and in cbk it removes each of
    the inode-ctx from the list. When the first such member is removed
    from the list it tries to modifies list head's memory with the
    latest next/prev and when this happens, there is no guarantee
    that the stack memory is valid.

    Fix:
    Do list_del_init() in the loop before winding fsync.
