[PATCH] ppc64: fix enable_surveillance() for power5 · d613adcd

Nathan Fontenot authored Aug 23, 2004

On some platforms (notably power5) you can't enable surveillance
(firmware/service processor watchdog) from the kernel - you have to do
it in the firmware.

This patch changes enable_surveillance() to make the message that is
printed in this situation more informative.  Additionaly, the rtas_call
was changed to rtas_set_indicator so as to avoid having to handle
RTAS_BUSY returns.

Use F_SETLK instead of F_SETLK64 in nfs locking code. · 6a8e8a44

Linus Torvalds authored Aug 23, 2004

The code doesn't actually _care_ about 32/64-bit issues,
only about F_SETLK vs F_SETLKW, and the F_SETLK64 doesn't
exist except as a compatibility thing on 64-bit architectures
(since the regular one already _is_ 64-bit, of course).

NFSv2: In the NFSv3 RFC, the sattr3 structure passed in the SETATTR · e143b1c8

Trond Myklebust authored Aug 23, 2004

   call allows for the client to request that the mtime and/or atime
   of an inode be set to the current server time, the given (client)
   time, or not changed.  The set-to-current-server value is used
   when you run "touch file" on the client.

The NFSv2 RFC defines no such encoding for the sattr structure. 
   However Solaris and Irix machine obey a convention where passing
   the invalid value mtime.useconds=1000000 means "set both mtime and
   atime to the current server time".  The convention is documented
   in the book "NFS Illustrated" by Brent Callaghan.  The patch below
   implements this convention for the Linux client and server (hence
   multiple To:s).

NFS: In 2.4, NFS O_DIRECT used the VFS's O_DIRECT logic to provide · 4ea5dc72

Trond Myklebust authored Aug 23, 2004

   direct I/O support for NFS files.  The 2.4 VFS O_DIRECT logic was
   block based, thus the NFS client had to provide a minimum
   allowable blocksize for O_DIRECT reads and writes on NFS files. 
   For various reasons we chose 512 bytes. In 2.6, there is no
   requirement for a minimum blocksize.  NFS O_DIRECT reads and
   writes can go to any byte at any offset in a file.  Thus we revert
   the blocksize setting for NFS file systems to the previous
   behavior, which was to advertise the "wsize" setting as the
   optimal I/O block size.  This improves the performance of
   applications like 'cp' which use this value as their transfer
   size.

This patch also exposes the server's reported disk block size in the
   f_frsize of the vfsstat structure.
