The top commit at the time of the failure was:

commit 5522aa1a4c34ee1a1e81db73cf41594bb10bd989
Author: Michael Adam <obnox at samba.org>

    vfs:glusterfs_fuse: ensure fileids are constant across nodes
    
    Instead of adding a new gluster-specific mode to the fileid module,
    this patches provides a fileid algorithm as part of the glusterfs_fuse
    vfs module. This can not be configured further, simply adding the
    glusterfs_fuse vfs module to the vfs objects configuration will enable
    the new fileid mode.
