[PATCH] remove many unneeded #includes of sched.h

2007-02-14T16:09:54+00:00

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

[PATCH] knfsd: SUNRPC: Provide room in svc_rqst for larger addresses

2007-02-12T17:48:36+00:00

Expand the rq_addr field to allow it to contain larger addresses.

Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then
everywhere the 'sockaddr_in' was referenced, we use instead an accessor
function (svc_addr_in) which safely casts the _storage to _in.

[PATCH] fs/lockd/host.c: make 2 functions static

Make the following needlessly global functions static:

 - nlm_lookup_host()
 - nsm_find()

[PATCH] knfsd: lockd: fix refount on nsm

2006-10-04T14:55:20+00:00

If nlm_lookup_host finds what it is looking for it exits with an extra
reference on the matching 'nsm' structure.

So don't actually count the reference until we are (fairly) sure it is going
to be used.

Both the (recently introduces) nsm_sema and the older f_sema are converted
over.

[PATCH] knfsd: lockd: optionally use hostnames for identifying peers

2006-10-04T14:55:17+00:00

This patch adds the nsm_use_hostnames sysctl and module param.  If set, lockd
will use the client's name (as given in the NLM arguments) to find the NSM
handle.  This makes recovery work when the NFS peer is multi-homed, and the
reboot notification arrives from a different IP than the original lock calls.

[PATCH] knfsd: simplify nlmsvc_invalidate_all

2006-10-04T14:55:17+00:00

As a result of previous patches, the loop in nlmsvc_invalidate_all just sets
h_expires for all client/hosts to 0 (though does it in a very complicated
way).

This was possibly meant to trigger early garbage collection but half the time
'0' is in the future and so it infact delays garbage collection.

Pre-aging the 'hosts' is not really needed at this point anyway so we throw
out the loop and nlm_find_client which is no longer needed.
