    [GFS2] Fix log entry list corruption · 68835625
    Benjamin Marzinski 提交于
    When glock_lo_add and rg_lo_add attempt to add an element to the log, they
    check to see if has already been added before locking the log. If another
    process adds that element to the log in this window between the check and
    locking the log, the element will be added to the list twice. This causes
    the log element list to become corrupted in such a way that the log element
    can never be successfully removed from the list. This patch pulls the
    list_empty() check inside the log lock, to remove this window.
