      btrfs: fix a deadlock in btrfs_scan_one_device() · 10f6327b
      Al Viro 提交于
      pathname resolution under a global mutex, taken on some paths in ->mount()
      is a Bad Idea(tm) - think what happens if said pathname resolution triggers
      automount of some btrfs instance and walks into attempt to grab the same
      mutex.  Deadlock - we are waiting for daemon to finish walking the path,
      daemon is waiting for us to release the mutex...

      btrfs: fix mount/umount race · 6de1d09d
      Al Viro 提交于
      Do *NOT* skip doomed superblocks in btrfs_test_super(); we want
      sget() to wait for their shutdown to complete.  Since we don't
      mutilate ->s_fs_info in ->put_super() anymore (or free what it
      used to point to until the superblock is past being findable
      by sget()), we can just DTRT there and report a match.

      ... and move free_fs_info() to that, out of ->put_super().  Do NOT
      set ->s_fs_info to NULL in the latter; we need it for sget() to
      be able to see and wait for fs in the middle of umount if we get a
      mount/umount race.

      btrfs: preparation to fixing mount/umount race · 98c7089c
      Al Viro 提交于
      We need fs_info and root to live until the moment when the victim
      superblock leaves the list, so we need to postpone free_fs_info()
      until after ->put_super().  The call is buried in close_ctree(),
      though, so we need to lift it into the callers (including
      btrfs_put_super()) first.

      the wants-replacement device will be removed.

      Fix up conflicts with 'struct sysdev' removal from various platform
      drivers that got changed:
       - arch/arm/mach-exynos/cpu.c
       - arch/arm/mach-exynos/irq-eint.c
       - arch/arm/mach-s3c64xx/common.c
       - arch/arm/mach-s3c64xx/cpu.c
       - arch/arm/mach-s5p64x0/cpu.c
       - arch/arm/mach-s5pv210/common.c
       - arch/arm/plat-samsung/include/plat/cpu.h
       - arch/powerpc/kernel/sysfs.c
      and fix up cpu_is_hotpluggable() as per Greg in include/linux/cpu.h
