Subject: [PATCH v3] Illuminate thread id to user space
Date: Mon, 03 Apr 2017 12:32:35 +0300	[thread overview]
Message-ID: <1491211956-6095-1-git-send-email-a.perevalov@samsung.com> (raw)
In-Reply-To: CGME20170403093307eucas1p2e1110dd2550426c53a7b8825efa34f99@eucas1p2.samsung.com


Hi Andrea,

This is third version of the patch. Modifications since previous versions:
	(v3 -> v2)
 - type of ptid now is __u32. As you suggested.

	(v2 -> v1)
 - process thread id is provided only when it was requested with
UFFD_FEATURE_THREAD_ID bit.
 - pid from namespace is provided, so locking thread's gettid in namespace
and msg.arg.pagefault.ptid will be equal. 

This patch is based on
git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git userfault branch.
HEAD commit is "userfaultfd: switch to exclusive wakeup for blocking reads"
