This renders the FMLP and SRP unfunctional until they are ported to
the new locking API.
|
| |
|
|
| |
Passing the object type explicitly will enable generic lock constructors.

1) High priority task tied to FMLP semaphore in P-EDF scheduling is
incorrectly tracked for tasks acquiring the lock without
contention. (HP is always set to CPU 0 instead of proper CPU.)
2) Race in a print statement from P-EDF's pi_block() causes NULL
pointer dereference.
