      mm, page_alloc: Add missing check for memory holes · b4fb8f66
      Tony Luck 提交于
      Commit 13ad59df ("mm, page_alloc: avoid page_to_pfn() when merging
      buddies") moved the check for memory holes out of page_is_buddy() and
      had the callers do the check.
      
      But this wasn't done correctly in one place which caused ia64 to crash
      very early in boot.
      
      Update to fix that and make ia64 boot again.
      
      [ v2: Vlastimil pointed out we don't need to call page_to_pfn()
            since we already have the result of that in "buddy_pfn" ]

      Merge tag 'ktest-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest · 8557b8e4
      Linus Torvalds 提交于
      Pull ktest fixes from Steven Rostedt:
       "Greg Kroah-Hartman reported to me that the ktest of v4.11-rc1 locked
        up in an infinite loop while doing the make mrproper.
      
        Looking into the cause I noticed that a recent update to the function
        run_command (used for running all shell commands, including "make
        mrproper") changed the internal loop to use the function
        wait_for_input.
      
        The wait_for_input function uses select to look at two file
        descriptors. One is the file descriptor of the command it is running,
        the other is STDIN. The STDIN check was not checking the return status
        of the sysread call, and was also just writing a lot of data into
        syswrite without regard to the size of the data read.
      
        Changing the code to check the return status of sysread, and also to
        still process the passed in descriptor data without looping back to
        the select fixed Greg's problem.
      
        While looking at this code I also realized that the loop did not honor
        the timeout if STDIN always had input (or for some reason return
        error). this could prevent wait_for_input to timeout on the file
        descriptor it is suppose to be waiting for. That is fixed too"

      overlayfs: remove now unnecessary header file include · 04bb94b1
      Linus Torvalds 提交于
      This removes the extra include header file that was added in commit
      e58bc927 "Pull overlayfs updates from Miklos Szeredi" now that it
      is no longer needed.
      
      There are probably other such includes that got added during the
      scheduler header splitup series, but this is the one that annoyed me
      personally and I know about.

      sched/headers: fix up header file dependency on <linux/sched/signal.h> · bd0f9b35
      Linus Torvalds 提交于
      The scheduler header file split and cleanups ended up exposing a few
      nasty header file dependencies, and in particular it showed how we in
      <linux/wait.h> ended up depending on "signal_pending()", which now comes
      from <linux/sched/signal.h>.
      
      That's a very subtle and annoying dependency, which already caused a
      semantic merge conflict (see commit e58bc927 "Pull overlayfs updates
      from Miklos Szeredi", which added that fixup in the merge commit).
      
      It turns out that we can avoid this dependency _and_ improve code
      generation by moving the guts of the fairly nasty helper #define
      __wait_event_interruptible_locked() to out-of-line code.  The code that
      includes the signal_pending() check is all in the slow-path where we
      actually go to sleep waiting for the event anyway, so using a helper
      function is the right thing to do.
      
      Using a helper function is also what we already did for the non-locked
      versions, see the "__wait_event*()" macros and the "prepare_to_wait*()"
      set of helper functions.
      
      We might want to try to unify all these macro games, we have a _lot_ of
      subtly different wait-event loops.  But this is the minimal patch to fix
      the annoying header dependency.
