[PATCH] futex-2.5.42-A2
This is my current futex patchset against BK-curr. It mostly includes must-have crash/correctness fixes from Martin Wirth, tested and reworked somewhat by myself: - crash fix: futex_close did not detach from the vcache. Detach cleanups. (Martin Wirth) - memory leak fix: forgotten put_page() in a rare path in __pin_page(). (Martin Wirth) - crash fix: do not do any quickcheck in unqueue_me(). (Martin, me) - correctness fix: the fastpath in __pin_page() now handles reserved pages the same way get_user_pages() does. (Martin Wirth) - queueing improvement: __attach_vcache() now uses list_add_tail() to avoid the reversal of the futex queue if a COW happens. (Martin Wirth) - simplified alignment check in sys_futex. (Martin Wirth) - comment fix: make it clear how the vcache hash quickcheck works. (me)
