Thanks for taking a look, but I don't see the issue here:

# /opt/ltp/testcases/bin/mmap01 -i4
tst_tmpdir.c:316: TINFO: Using /tmp/LTP_mmaiVJsAq as tmpdir (fuse filesystem)

Summary:

I appended the "YES" just to make sure I wasn't running some outdated
code, can you please provide more details?


Thanks!
