I'm trying to debug a phantom I/O error which I mentioned before (https://lists.samba.org/archive/samba/2023-March/244431.html - it turned out it has nothing to do with kernel oplocks). And noticed samba is regularly tries to load libgpfs.so. This is done in gpfswrap_init() in lib/util/gpfswrap.c, which is used in vfs_gpfs.c (understandable) *and* in lib/util/debug.c.
