And how it will be a cleanup?
The whole cow code (and a few others) is not reenterant. Merely
moving this lock/unlock stuff inth actual methods eliminates two
current wrappers in cow_co_write() and cow_co_read(), which are
exactly the same

More or less trivial conversion.
This also fixes a few bugs in several block drivers which
provide only read but not write or the reverse. The code
allowed to use such drivers in readwrite mode. Affected
drivers: bochs, cloop, dmg, parallels, vvfat_write_target.
Some block drivers gained
