Date: Thu, 25 Feb 2021 15:50:52 -0600 [thread overview]
Message-ID: <20210225215057.23020-1-tyreld@linux.ibm.com> (raw)
This series contains a minor simplification of ibmvfc_init_sub_crqs() followed
by a couple fixes for sub-CRQ handling which effect hard reset of the
client/host adapter CRQ pair.
changes in v4:
Patch 2: dropped Reviewed-by tag and moved sub-crq init to after locked region
Patch 5: moved sub-crq init to after locked region
changes in v3:
* Patch 1 & 5: moved ibmvfc_init_sub_crqs out of locked patch
changes in v2:
* added Reviewed-by tags for patches 1-3
* Patch 4: use rtas_busy_delay to test rc and delay correct amount of time
* Patch 5: (new) similar fix for LPM case where CRQ pair needs re-enablement
Tyrel Datwyler (5):
powerpc/pseries: extract host bridge from pci_bus prior to bus removal
ibmvfc: simplify handling of sub-CRQ initialization
ibmvfc: fix invalid sub-CRQ handles after hard reset
ibmvfc: treat H_CLOSED as success during sub-CRQ registration
ibmvfc: store return code of H_FREE_SUB_CRQ during cleanup
