Subject: tail,stat: improve support for vmhgfs
X-Git-Tag: v8.20~31
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2dad87f6415ec68564e934ace33496db1abc68c7;p=thirdparty%2Fcoreutils.git

tail,stat: improve support for vmhgfs

Teach tail -f that it must use polling on vmhgfs file systems, and
let stat -f --format=%T report the file system type name, "vmhgfs".
* src/stat.c (human_fstype): Add a case: vmhgfs, 0xbacbacbc, remote.
* NEWS (Improvements): Mention it.
* THANKS.in: Update.

-  stat and tail work better with ZFS and VZFS.  stat -f --format=%T now
-  reports the file system type, and tail -f now uses inotify for files
-  on those file systems, rather than the default (for unknown file system
-  types) of issuing a warning and reverting to polling.
+  stat and tail know about ZFS, VZFS and VMHGFS.  stat -f --format=%T now
+  reports the file system type, and tail -f now uses inotify for files on
+  ZFS and VZFS file systems, rather than the default (for unknown file
+  system types) of issuing a warning and reverting to polling.  tail -f
