md: avoid deadlock when md_set_badblocks.
When operate harddisk and hit errors, md_set_badblocks is called after
scsi_restart_operations which already disabled the irq. but md_set_badblocks
will call write_sequnlock_irq and enable irq. so softirq can preempt the
current thread and that may cause a deadlock. I think this situation should
use write_sequnlock_irqsave/irqrestore instead.
This bug was introduce in commit 2e8ac30312973dd20e68073653
(the first time rdev_set_badblock was call from interrupt context),
so this patch is appropriate for 3.5 and subsequent kernels.
spares are activated on a read-only array. In case of raid1 and raid10
personalities it causes that not-in-sync devices are marked in-sync
without checking if recovery has been finished.
If a read-only array is degraded and one of its devices is not in-sync
(because the array has been only partially recovered) recovery will be skipped.
This patch adds checking if recovery has been finished before marking a device
in-sync for raid1 and raid10 personalities. In case of raid5 personality
such condition is already present (at raid5.c:6029).
Bug was introduced in 3.10 and causes data corruption.

xfs_trans.h has a dependency on xfs_log.h for a couple of

include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header
files and clean up the includes to be in dependency order.
In doing this, remove the direct include of xfs_trans_reserve.h from
xfs_trans.h so that we remove the dependency between xfs_trans.h and
xfs_mount.h. Hence the xfs_trans.h include can be moved to the
indicate the actual dependencies other header files have on it.

Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge
Antonio Quartulli says:
====================
this is another set of changes intended for net-next/linux-3.13.
(probably our last pull request for this cycle)
Patches 1 and 2 reshape two of our main data structures in a way that they can
easily be extended in the future to accommodate new routing protocols.
Patches from 3 to 9 improve our routing protocol API and its users so that all
the protocol-related code is not mixed up with the other components anymore.
Patch 10 limits the local Translation Table maximum size to a value such that it
can be fully transfered over the air if needed. This value depends on
fragmentation being enabled or not and on the mtu values.
Patch 11 makes batman-adv send a uevent in case of soft-interface destruction
while a "bat-Gateway" was configured (this informs userspace about the GW not
being available anymore).
Patches 13 and 14 enable the TT component to detect non-mesh client flag
changes at runtime (till now those flags where set upon client detection and
were not changed anymore).
Patch 16 is a generalisation of our user-to-kernel space communication (and
viceversa) used to exchange ICMP packets to send/received to/from the mesh
network. Now it can easily accommodate new ICMP packet types without breaking
the existing userspace API anymore.
Remaining patches are minor changes and cleanups.

Defer the generation of the first hash secret for the ipv4 fragmentation

ip4_frags.rnd gets initial seeded by inet_frags_init and regulary
reseeded by inet_frag_secret_rebuild. Either we call ipqhashfn directly
from ip_fragment.c in which case we initialize the secret directly.
If we first get called by inet_frag_secret_rebuild we install a new secret
by a manual call to get_random_bytes. This secret will be overwritten
as soon as the first call to ipqhashfn happens. This is safe because we
won't race while publishing the new secrets with anyone else.
