Routine Description:
|

|
|
|
|||
|
|
This routine is called from the RDBSS whenever the fsrtl lock package calls the rdbss unlock routine.
|

|
|
CODE.IMPROVEMENT what should really happen is that this should only be called for unlockall and unlockbykey;
|

|
|
the other cases should be handled in the rdbss.

Arguments:

|
|
Context - the RxContext associated with this request
|
|||
|
|
LockInfo - gives information about the particular range being unlocked
|
