Modified files:
sys/kern subr_witness.c
Log:
Add "show alllocks" command to DDB, which dumps a list of processes
and threads currently holding sleep mutexes (and spin mutexes for
curthread). This can be quite useful in looking for a lock condition
summary for a system, as it avoids manually iterating through threads
and processes to find all the interesting locks.
NB: "alllocks" is up there with "lockedvnods" for a bad argument for
show.
