      net: Add frag_list support to skb_segment · 89319d38
      Herbert Xu authored 
      This patch adds limited support for handling frag_list packets in
skb_segment.  The intention is to support GRO (Generic Receive Offload)
packets which will be constructed by chaining normal packets using
frag_list.

As such we require all frag_list members terminate on exact MSS
boundaries.  This is checked using BUG_ON.

As there should only be one producer in the kernel of such packets,
namely GRO, this requirement should not be difficult to maintain.

      cgroups: fix a race between rmdir and remount · 307257cf
      Paul Menage authored 
      When a cgroup is removed, it's unlinked from its parent's children list,
but not actually freed until the last dentry on it is released (at which
point cgrp->root->number_of_cgroups is decremented).

Currently rebind_subsystems checks for the top cgroup's child list being
empty in order to rebind subsystems into or out of a hierarchy - this can
result in the set of subsystems bound to a hierarchy being
removed-but-not-freed cgroup.

The simplest fix for this is to forbid remounts that change the set of
subsystems on a hierarchy that has removed-but-not-freed cgroups.  This
bug can be reproduced via:

mkdir /mnt/cg
mount -t cgroup -o ns,freezer cgroup /mnt/cg
mkdir /mnt/cg/foo
sleep 1h < /mnt/cg/foo &
rmdir /mnt/cg/foo
mount -t cgroup -o remount,ns,devices,freezer cgroup /mnt/cg
kill $!

Though the above will cause oops in -mm only but not mainline, but the bug
can cause memory leak in mainline (and even oops)

      ACPI toshiba: only register rfkill if bt is enabled · 38aefbc5
      Frederik Deweerdt authored 
      Part of the rfkill initialization was done whenever BT was on or not.  The
following patch checks for BT presence before registering the rfkill to
the input layer.  Some minor cleanups (> 80 char lines) were also added in
the process.

      slob: do not pass the SLAB flags as GFP in kmem_cache_create() · 5e18e2b8
      Catalin Marinas authored 
      The kmem_cache_create() function in the slob allocator passes the SLAB
flags as GFP flags to the slob_alloc() function.  The patch changes this
call to pass GFP_KERNEL as the other allocators seem to do.
