| * | block, drivers, fs: rename REQ_FLUSH to REQ_PREFLUSH | Mike Christie | 2016-06-07 | 1 | -5/+5 |
| | | | | | | | | | | | | | To avoid confusion between REQ_OP_FLUSH, which is handled by request_fn drivers, and upper layers requesting the block layer perform a flush sequence along with possibly a WRITE, this patch renames REQ_FLUSH to REQ_PREFLUSH.

| * | dm: add log writes target | Josef Bacik | 2015-04-15 | 1 | -0/+140 |
| Introduce a new target that is meant for file system developers to test file system integrity at particular points in the life of a file system. We capture all write requests and associated data and log them to a separate device for later replay. There is a userspace utility to do this replay. The idea behind this is to give file system developers a tool to verify that the file system is always consistent.
