This patch set removes the unused vma argument in update_page_range

dentry lock reported by lockdep.

drivers/android/binder_alloc.c | 36 ++
Use binder_alloc struct's mm_struct rather than getting
a reference to the mm struct through get_task_mm to
avoid a potential deadlock between lru lock, task lock and
dentry lock, since a thread can be holding the task lock
and the dentry lock while trying to acquire the lru lock.

The vma argument in update_page_range is no longer
used after 74310e06 ("android: binder: Move buffer

On a powerpc system with pkeys support, here is what is shown:

Currently the architecture specific code is expected to

This can lead to redundant code and possibly to divergent
formats in which the key gets displayed.
This patch changes the implementation. It displays the
pkey only if the archite

For active sockets, check the indexes and use the inflight_conn_req
waitqueue to wait.
For passive sockets if an accept is outstanding
(PVCALLS_FLAG_ACCEPT_INFLIGHT), check if it has been answered by looking
at bedata->rsp[req_id]. If so, return POLLIN. Otherwise use the

Introduce a data structure named pvcalls_bedata. It contains pointers to
the command ring, the event channel, a list of active sockets and a list
of passive sockets. Lists accesses are protected by a spin_lock.

to the backend.

Send PVCALLS_RELEASE to the backend and wait for a reply. Take both

For passive sockets, check whether we have already pre-allocated an
active socket for the purpose of being accepted. If so, free that as
well.

Hi all,
this series introduces the frontend for the newly introduced PV Calls
procotol.
PV Calls is a paravirtualized protocol that allows the implementation of
a set of POSIX functions in a different domain. The PV Calls frontend
sends POSIX function calls to the backend, which implements them a
I'm announcing the release of the 3.2.93 kernel.
