2006-01-06[PATCH] s390: re-activated path detectionCornelia Huck1-0/+15
If we receive path not operational indications (pnom in pmcw nonzero), we switch off those paths. To catch them becoming available again, we have to recalculate the lpm from the pmcw each time we start path verification.

2006-01-06[PATCH] s390: atomic primitivesMartin Schwidefsky7-24/+22
Hugh Dickins <hugh@veritas.com> 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.

2005-10-31[PATCH] fix missing includesTim Schmielau3-0/+6
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

This patch introduces new feature in qeth: qeth enhancement provides the device driver support for the Communication Controller for Linux on System z9 and zSeries (CCL), which is software that enables running the Network Control Program (NCP) on a zSeries machine. The OSA CDLC support is based on a new IBM mainframe CHPID type called Open Systems Adaper for NCP (OSN). In case of OSN qeth communicates with the type-OSN OSA-card on one hand, and with the CCL-kernel-component Network Device Handler (NDH) on the other.

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and introduces __in_dev_get_rcu() to cover the second case. 1) RCU with refcnt should use in_dev_get(). 2) RCU without refcnt should use __in_dev_get_rcu(). 3) All others must hold RTNL and use __in_dev_get_rtnl().

The new traces improve debugging of problems with zfcp, scsi-stack, multipath and hardware in the SAN. san_dbf traces things like ELS and CT commands, hba_dbf saves HBA specific information of requests, and scsi_dbf saves FCP and SCSI specific information of requests. Common to all new DBFs is that they provide a so called structured view. This significantly improves readability of the traces.
