[PATCH 0/7] ldsem patchset

From: Peter Hurley
Date: Tue Mar 19 2013 - 16:05:28 EST

Ingo and David,

Greg has asked me to get your acks on the r/w semaphore implementation
in the first patch,
'tty: Add timed, writer-prioritized rw_semaphore'

Would you please review the implementation and comment?

This is a re-spin of the remainder of 'ldisc patchset'.
The semaphore-related patches of that set have been squashed into the
first patch.

Sasha and Dave,

Please don't run the 44-patch ldisc patchset anymore. That patchset
was only partially applied so trinity testing for linux-next may
give false assurance that those bugs are fixed.

Peter Hurley (7):
tty: Add timed, writer-prioritized rw semaphore
tty: Add lock/unlock ldisc pair functions
tty: Replace ldisc locking with ldisc_sem
tty: Clarify ldisc variable
tty: Fix hangup race with TIOCSETD ioctl
tty: Clarify multiple-references comment in TIOCSETD ioctl
tty: Fix tty_ldisc_lock name collision
