      Fix up MAINTAINERS file sorting · 3882a734
      Linus Torvalds authored
      Another merge window, another MAINTAINERS file disaster.
      
      People have serious problems with the alphabet and sorting, and poor
      Jérôme Glisse and Radim Krčmář get their names mangled by locale issues,
      turning them into some mangled mess (probably others do too, but those
      two stood out when sorting things again).
      
      And we now have two copies of the same 'AS3645A LED FLASH CONTROLLER
      DRIVER' in the tree and in the MAINTAINERS file, but that's a separate
      issue - the duplication is real, and I left them as two entries for the
      same name.
      
      This does not try to sort the actual section pattern entries, although I
      may end up doing that later.

       "The diff is dominated by the Allwinner A10/A20 SoCs getting converted
        to the sunxi-ng framework. Otherwise, the heavy hitters are various
        drivers for SoCs like AT91, Amlogic, Renesas, and Rockchip. There are
        some other new clk drivers in here too but overall this is just a
        bunch of clk drivers for various different pieces of hardware and a
        collection of non-critical fixes for clk drivers.

      xfs: XFS_IS_REALTIME_INODE() should be false if no rt device present · b31ff3cd
      Richard Wareing authored
      If using a kernel with CONFIG_XFS_RT=y and we set the RHINHERIT flag on
      a directory in a filesystem that does not have a realtime device and
      create a new file in that directory, it gets marked as a real time file.
      When data is written and a fsync is issued, the filesystem attempts to
      flush a non-existent rt device during the fsync process.
      
      This results in a crash dereferencing a null buftarg pointer in
      xfs_blkdev_issue_flush():
      
        BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
        IP: xfs_blkdev_issue_flush+0xd/0x20
        .....
        Call Trace:
          xfs_file_fsync+0x188/0x1c0
          vfs_fsync_range+0x3b/0xa0
          do_fsync+0x3d/0x70
          SyS_fsync+0x10/0x20
          do_syscall_64+0x4d/0xb0
          entry_SYSCALL64_slow_path+0x25/0x25
      
      Setting RT inode flags does not require special privileges so any
      unprivileged user can cause this oops to occur.  To reproduce, confirm
      kernel is compiled with CONFIG_XFS_RT=y and run:
      
        # mkfs.xfs -f /dev/pmem0
        # mount /dev/pmem0 /mnt/test
        # mkdir /mnt/test/foo
        # xfs_io -c 'chattr +t' /mnt/test/foo
        # xfs_io -f -c 'pwrite 0 5m' -c fsync /mnt/test/foo/bar
      
      Or just run xfstests with MKFS_OPTIONS="-d rtinherit=1" and wait.
      
      Kernels built with CONFIG_XFS_RT=n are not exposed to this bug.
