sys/geom/mirror g_mirror.c g_mirror.h
Log:
MFC:
- Avoid race while synchronizing components. It is very hard to bump into,
but it is possible:
1. Read data from good component for synchronization.
2. Write data to the same area.
3. Write synchronization data, which are now stale.
- Decrease kern.geom.mirror.timeout to 4, so it is smaller than
vfs.root.mountdelay by default.
- Don't skip providers with 0 sectorsize.
