The patch titled Subject: fs/proc/task_mmu.c: update m->version in the main loop in m_start() has been added to the -mm tree. Its filename is fs-proc-task_mmuc-update-m-version-in-the-main-loop-in-m_start.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/fs-proc-task_mmuc-update-m-version-in-the-main-loop-in-m_start.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/fs-proc-task_mmuc-update-m-version-in-the-main-loop-in-m_start.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/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Oleg Nesterov <oleg@xxxxxxxxxx> Subject: fs/proc/task_mmu.c: update m->version in the main loop in m_start() Change the main loop in m_start() to update m->version. Mostly for consistency, but this can help to avoid the same loop if the very 1st ->show() fails due to seq_overflow(). Signed-off-by: Oleg Nesterov <oleg@xxxxxxxxxx> Cc: Kirill A.
