      ext4: check bh in ext4_read_block_bitmap() · 15b49132
      Eryu Guan authored
      Validate the bh pointer before using it, since
      ext4_read_block_bitmap_nowait() might return NULL.
      
      I've seen this in fsfuzz testing.

      ext4: use unlikely to improve the efficiency of the kernel · aebf0243
      Wang Shilong authored
      Because the function 'sb_getblk' seldomly fails to return NULL
      value,it will be better to use 'unlikely' to optimize it.

      ext4: return ENOMEM if sb_getblk() fails · 860d21e2
      Theodore Ts'o authored
      The only reason for sb_getblk() failing is if it can't allocate the
      buffer_head.  So ENOMEM is more appropriate than EIO.  In addition,
      make sure that the file system is marked as being inconsistent if
      sb_getblk() fails.

      Pull ARM SoC fixes from Olof Johansson:
       "People are back from the holiday breaks, and it shows.  Here are a
        bunch of fixes for a number of platforms:
         - A couple of small fixes for Nomadik
         - A larger set of changes for kirkwood/mvebu
           - uart driver selection, dt clocks, gpio-poweroff fixups, a few
             __init annotation fixes and some error handling improvement in
             their xor dma driver.
         - i.MX had a couple of minor fixes (and a critical one for flexcan2
           clock setup)
         - MXS has a small board fix and a framebuffer bugfix
         - A set of fixes for Samsung Exynos, fixing default bootargs and some
           Exynos5440 clock issues
         - A set of OMAP changes including PM fixes and a few sparse warning
           fixups
      
        All in all a bit more positive code delta than we'd ideally want to
        see here, mostly from the OMAP PM changes, but nothing overly crazy."
