    GFS2: Make rename not save dirent location · 19aeb5a6

    This patch fixes a regression in the patch "GFS2: Remember directory
    insert point", commit 2b47dad8.
    The problem had to do with the rename function: The function found
    space for the new dirent, and remembered that location. But then the
    old dirent was removed, which often moved the eligible location for
    the renamed dirent. Putting the new dirent at the saved location
    caused file system corruption.
    
    This patch adds a new "save_loc" variable to struct gfs2_diradd.
    If 1, the dirent location is saved. If 0, the dirent location is not
    saved and the buffer_head is released as per previous behavior.
