Each VF employees a lock that's supposed to serialize its usage of the HW channel for communication with its PF, but the critical section is ill-defined: - VFs currently release the lock whenever the PF response arrives, prior to actually processing the reply buffer [which was also supposed to have been protected by same lock]. - The lock would be released on first response, ignoring the possibilty the sw flow isn't over [as might be the case of the acquisition flow]. As a result, the flow would run unprotected and would cause a double mutex release [as the additional message completion would release it while its actually already free]. Change the flow to have a dedicated function to be called at end of each flow and release the lock. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.
