Revision af5a30d8cfcfc561336f982b06345d6b815e0bb3 authored by Nick Piggin on 03 June 2010, 12:01:46 UTC, committed by Al Viro on 04 June 2010, 21:16:30 UTC
mtime and ctime should be changed only if the file size has actually changed. Patches changing ext2 and tmpfs from vmtruncate to new truncate sequence has caused regressions where they always update timestamps. There is some strange cases in POSIX where truncate(2) must not update times unless the size has acutally changed, see 6e656be89. This area is all still rather buggy in different ways in a lot of filesystems and needs a cleanup and audit (ideally the vfs will provide a simple attribute or call to direct all filesystems exactly which attributes to change). But coming up with the best solution will take a while and is not appropriate for rc anyway. So fix recent regression for now.

help
Choose Y here if you want to allow other computers to access
files residing on this system using Sun's Network File System
protocol. To compile the NFS server support as a module,
choose M here: the module will be called nfsd.
You may choose to use a user-space NFS server instead, in which
case you can choose N here.
To export local file systems using NFS, you also need to install
user space programs which can be found in the Linux nfs-utils
package, available from http://linux-nfs.org/. More detail about
the Linux NFS server implementation is available via the
exports(5) man page.
Below you can choose which versions of the NFS protocol are
available to clients mounting the NFS server on this system.
Support for NFS version 2 (RFC 1094) is always available when
CONFIG_NFSD is selected.
If unsure, say N.

This option enables support in your system's NFS server for
version 3 of the NFS protocol (RFC 1813).
If unsure, say Y.

help
Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
never became an official part of the NFS version 3 protocol.
This protocol extension allows applications on NFS clients to
manipulate POSIX Access Control Lists on files residing on NFS
servers. NFS servers enforce POSIX ACLs on local files whether
this protocol is available or not.
This option enables support in your system's NFS server for the
NFSv3 ACL protocol extension allowing NFS clients to manipulate
POSIX ACLs on files exported by your system's NFS server. NFS
clients which support the Solaris NFSv3 ACL protocol can then
access and modify ACLs on your NFS server.
To store ACLs on your NFS server, you also need to enable ACL-
related CONFIG options for your local file systems of choice.
If unsure, say N.

help
This option enables support in your system's NFS server for
version 4 of the NFS protocol (RFC 3530).
To export files using NFSv4, you need to install additional user
space programs which can be found in the Linux nfs-utils package,
available from http://linux-nfs.org/.
If unsure, say N.
