      [parisc] open(2) compat bug · 25a3bc6b

      In commit 9d73fc2d ("open*(2) compat fixes (s390, arm64)") I said:

      Three exceptions, actually - parisc open() is another case like that.
      Native 32bit won't force O_LARGEFILE, the same binary on parisc64 will.

      Revert "sched, autogroup: Stop going ahead if autogroup is disabled" · fd8ef117
      Mike Galbraith authored
      This reverts commit 800d4d30.
      
      Between commits 8323f26c ("sched: Fix race in task_group()") and
      800d4d30 ("sched, autogroup: Stop going ahead if autogroup is
      disabled"), autogroup is a wreck.
      
      With both applied, all you have to do to crash a box is disable
      autogroup during boot up, then reboot..  boom, NULL pointer dereference
      due to commit 800d4d30 not allowing autogroup to move things, and
      commit 8323f26c making that the only way to switch runqueues:

      Merge branch 'block-dev' · d3594ea2
      Linus Torvalds authored
      Merge 'block-dev' branch.
      
      I was going to just mark everything here for stable and leave it to the
      3.8 merge window, but having decided on doing another -rc, I migth as
      well merge it now.
      
      This removes the bd_block_size_semaphore semaphore that was added in
      this release to fix a race condition between block size changes and
      block IO, and replaces it with atomicity guaratees in fs/buffer.c
      instead, along with simplifying fs/block-dev.c.
      
      This removes more lines than it adds, makes the code generally simpler,
      and avoids the latency/rt issues that the block size semaphore
      introduced for mount.
      
      I'm not happy with the timing, but it wouldn't be much better doing this
      during the merge window and then having some delayed back-port of it
      into stable.
      
      * block-dev:
        blkdev_max_block: make private to fs/buffer.c
        direct-io: don't read inode->i_blkbits multiple times
        blockdev: remove bd_block_size_semaphore again
        fs/buffer.c: make block-size be per-page and protected by the page lock
