OK, given GlusterFS v3.7.6 with the following patches:
===
Kaleb S KEITHLEY (1):
fuse: use-after-free fix in fuse-bridge, revisited
Pranith Kumar K (1):
mount/fuse: Fix use-after-free crash
Soumya Koduri (3):
gfapi: Fix inode nlookup counts
inode: Retire the inodes from the lru list in inode_table_destroy
upcall: free the xdr* allocations
===
I've repeated "rsync" test under Valgrind, and here is Valgrind output:
