Subject: + mm-gup-remove-task_struct-pointer-for-all-gup-code.patch added to -mm tree
Date: Wed, 08 Jul 2020 17:07:33 -0700
Message-ID: <20200709000733.R36-4HsTs%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200703151445.b6a0cfee402c7c5c4651f1b1@linux-foundation.org>


The patch titled
     Subject: mm/gup: remove task_struct pointer for all gup code
has been added to the -mm tree.  Its filename is
     mm-gup-remove-task_struct-pointer-for-all-gup-code.patch

This patch should soon appear at
    http://ozlabs.org/~akpm/mmots/broken-out/mm-gup-remove-task_struct-pointer-for-all-gup-code.patch
and later at
    http://ozlabs.org/~akpm/mmotm/broken-out/mm-gup-remove-task_struct-pointer-for-all-gup-code.patch

Before you just go and hit "reply", please:
   a) Consider who else should be cc'ed
   b) Prefer to cc a suitable mailing list as well
   c) Ideally: find the original patch on the mailing list and do a
      reply-to-all to that, adding suitable additional cc's

*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***

The -mm tree is included into linux-next and is updated
there every 3-4 working days

Subject: mm/gup: remove task_struct pointer for all gup code

After the cleanup of page fault accounting, gup does not need to pass
task_struct around any more.  Remove that parameter in the whole gup
stack.
