| Subject: ext4: initialize retries variable in ext4_da_write_inline_data_begin() |
| |
| 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. |
