    ext4: fix big-endian bugs which could cause fs corruptions · 8cde7ad1
    Zheng Liu authored
    When an extent was zeroed out, we forgot to do convert from cpu to le16.
    It could make us hit a BUG_ON when we try to write dirty pages out.  So
    fix it.
    
    [ Also fix a bug found by Dmitry Monakhov where we were missing
      le32_to_cpu() calls in the new indirect punch hole code.
    
      There are a number of other big endian warnings found by static code
      analyzers, but we'll wait for the next merge window to fix them all
      up.  These fixes are designed to be Obviously Correct by code
      inspection, and easy to demonstrate that it won't make any
      difference (and hence, won't introduce any bugs) on little endian
      architectures such as x86.  --tytso ]
