[ 040/167] [PATCH] ext4: fix endianness breakage in ext4_split_extent_at()

[Ben Hutchings]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>

commit af1584f570b19b0285e4402a0b54731495d31784 upstream.

->ee_len is __le16, so assigning cpu_to_le32() to it is going to do
Bad Things(tm) on big-endian hosts...
