[PATCH] sysctl: remove insert_at_head from register_sysctl

2007-02-14T16:09:59+00:00

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

[PATCH] sysctl: netrom: remove unnecessary insert_at_head flag

2007-02-14T16:09:55+00:00

The sysctl numbers used are unique so setting the insert_at_head flag serves
no semantic purpose, so it is just confusing.

[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] mark struct file_operations const 8

2007-02-12T17:48:46+00:00

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

[AX.25]: Fix unchecked ax25_linkfail_register uses

2006-12-18T05:59:11+00:00

ax25_linkfail_register uses kmalloc and the callers were ignoring the
error value.  Rewrite to let the caller deal with the allocation.  This
allows the use of static allocation of kmalloc use entirely.

[AX.25]: Fix unchecked ax25_protocol_register uses.

2006-12-18T05:59:08+00:00

Replace ax25_protocol_register by ax25_register_pid which assumes the
caller has done the memory allocation.  This allows replacing the
kmalloc allocations entirely by static allocations.

[AX.25]: Mark all kmalloc users __must_check

2006-12-18T05:59:07+00:00

The recent fix 0506d4068bad834aab1141b5dc5e748eb175c6b3 made obvious that
error values were not being propagated through the AX.25 stack.  To help
with that this patch marks all kmalloc users in the AX.25, NETROM and
ROSE stacks as __must_check.
