4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lukas Czerner lczerner@redhat.com
commit 625ef8a3acd111d5f496d190baf99d1a815bd03e upstream.
Variable retries is not initialized in ext4_da_write_inline_data_begin() which can lead to nondeterministic number of retries in case we hit ENOSPC. Initialize retries to zero as we do everywhere else.
