HSM Release is one of the key feature of HSM. To perform HSM
release, clients need to acquire the file lease exclusivelt and
flush dirty cache from clients. A special close REQ will be sent
to the MDT to release the lease and get rid of OST objects.

staging/lustre/ptlrpc: Fix a crash when dereferencing NULL pointer
When a system runs out of memory and the function
ptlrpc_register_bulk() is called from ptl_send_rpc() the call to
LNetMEAttach() fails due to failure to allocate memory. This forces
the code into an error path, which most probably previously went
untested. The error path:
if (rc != 0) {
CERROR("%s: LNetMEAttach failed x"LPU64"/%d: rc = %dn",
desc->bd_export->exp_obd->obd_name, xid,
posted_md, rc);
break;
}
This print assumes that desc->bd_export is not NULL. However, it is.
In fact it is expected to be NULL. desc->bd_import is the correct
structure to access in this case.

ll_lookup_it() checks for O_CREAT in struct lookup_intent's

for file mode bits (S_IFREG, S_IRUSR, ...). Fix this by just checking

Failure to grab reference to parent dentry should go through the
same cleanup as nd->seq mismatch. As it is, we might end up with
caller thinking it needs to path_put() nd->root, with obvious
nasty results once we'd hit that bug enough times to drive the
refcount of root dentry all the way to zero...

ALSA: hda - Check leaf nodes to find aamix amps
The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself. But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls. This is a regression
compared with the previous static quirks.
This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.
