Ah, sorry for the misunderstanding. I'll do a forced commit to clarify the message later today. Thanks for the help! Chris signature.asc Description: OpenPGP digital signature

No, these are checks to see if the userspace requested an update to the corresponding inode time and supplied valid time.

svn commit: r285885 - head/sys/fs/tmpfs
Author: brueffer Date: Sun Jul 26 08:33:46 2015 New Revision: 285885 URL: https://svnweb.freebsd.org/changeset/base/285885 Log: In tmpfs_chtimes(), remove checks on the nanosecond level when determining whether a node changed. Other filesystems, e.g., UFS, only check on seconds, when determining whether something changed. This also corrects the birthtime case, where we checked tv_nsec twice, instead of tv_sec and tv_nsec (PR).
