Author: asomers Date: Thu Mar 21 21:56:03 2019 New Revision: 345391 URL: https://svnweb.freebsd.org/changeset/base/345391 Log: MFC r340455, r340525, r341598 r340455: fcntl.2: document an additional error condition r340525: mount_fusefs.8: expand HISTORY section Note that fuse was available from ports long before joining the base system. Also, update the upstream URL. r341598: stat(2): clarify which syscalls modify file timestamps The list of syscalls that modify st_atim, st_mtim, and st_ctim was quite out of date and probably not accurate to begin with. Update it, and make it clear that the list is open-ended.
