Jeff Roberson 08023360a0 - Convert the global LK lock to a mutex. ... - Expand the scope of lk to cover not only interrupt races, but also top-half races, which includes many new uses over global top-half only data. - Get rid of interlocked_sleep() and use msleep or BUF_LOCK where appropriate. - Use the lk mutex in place of the various hand rolled semaphores. - Stop dropping the lk lock before we panic. - Fix getdirtybuf() callers so that they reacquire access to whatever softdep datastructure they were inxpecting in the failure/retry case. Previously, sleeps in getdirtybuf() could leave us with pointers to bad memory. - Update handling of ffs to be compatible with ffs locking changes.
