    libfshelp: destroy condition variable before freeing it
    
    To make sure that threads have really woken up.
    
    Spotted by Richard Braun.
    
    * libfshelp/rlock-drop-peropen.c (fshelp_rlock_drop_peropen): Call
    pthread_cond_destroy before freeing the condition variable.
    * libfshelp/rlock-tweak.c (fshelp_rlock_tweak): Likewise.

    libdiskfs: Add missing node lock around fshelp_rlock_drop_peropen call
    
    fshelp_rlock_drop_peropen actually needs the node to be locked for
    proper waiting atomicity.

commit 9e3b662812cebe8113a144c705eddbbd3855f54b
Author: Samuel Thibault <samuel.thibault@ens-lyon.org>
Date:   Mon Jun 1 18:35:28 2020 +0200

    libdiskfs: Drop spurious mutex acquisition
    
    diskfs_make_peropen does not need node to be locked. Worse, it could try to
    lock it.
    
    * libdiskfs/file-reparent.c (diskfs_S_file_reparent): Do not lock node
    around diskfs_make_peropen.
