2006-07-12[S390] path grouping and path verifications fixes.Cornelia Huck1-0/+1
1. Multipath devices for which SetPGID is not supported are not handled well. Use NOP ccws for path verification (sans path grouping) when SetPGID is not supported. 2. Check for PGIDs already set with SensePGID on _all_ paths (not just the first one) and try to find a common one. Moan if no common PGID can be found (and use NOP verification). If no PGIDs have been set, use the css global PGID (as before). (Rationale: SetPGID will get a command reject if the PGID it tries to set does not match the already set PGID.) 3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This will remove the old PGIDs. rcp will generate solicited CRWs which can be savely ignored by the machine check handler (all other actions create unsolicited CRWs).

2006-01-06[PATCH] s390: atomic primitivesMartin Schwidefsky1-1/+1
Hugh Dickins <[email protected]> Fix the broken atomic_cmpxchg primitive. Add atomic_sub_and_test, atomic64_sub_return, atomic64_sub_and_test, atomic64_cmpxchg, atomic64_add_unless and atomic64_inc_not_zero. Replace old style atomic_compare_and_swap by atomic_cmpxchg. Shorten the whole header by defining most primitives with the two inline functions atomic_add_return and atomic_sub_return. In addition this patch contains the s390 related fixes of Hugh's "mm: fill arch atomic64 gaps" patch.
