[PATCH 3.18 24/47] ext4: missing unlock/put_page() in ext4_try_to_write_inline_data()

[Greg Kroah-Hartman]

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

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

From: Maurizio Lombardi <mlomb...@redhat.com>

commit 132d00becb31e88469334e1e62751c81345280e0 upstream.

In case of error, ext4_try_to_write_inline_data() should unlock
and release the page it holds.

Fixes: f19d5870cbf7 ("ext4: add normal write support for inline data")
