* [PATCH] gfp flags annotations - part 1Al Viro2005-10-08
| | | | | | | | | | | | - added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

* [SCSI] zfcp: add additional fc_host attributesAndreas Herrmann2005-09-19
| | | | | | | | | | | | this patch adds some fc host attributes and removes its equivalents from the zfcp_adapter structure and zfcp specific sysfs subtree. Furthermore it removes superfluous calls to fc_remort_port_delete when an adapter is set offline because rports will be removed by fc_remove_host anyway.

* [SCSI] zfcp: provide support for NPIVMaxim Shchetynin2005-09-19
| | | | | | | | | | N_Port ID Virtualization (NPIV) allows a single FCP port to appear as multiple, distinct ports providing separate port identification. NPIV is supported by FC HBAs on System z9. zfcp was adapted to support this new feature.

* [SCSI] zfcp: enhancement of zfcp debug featuresMaxim Shchetynin2005-09-19
| | | | | | | | | | | | | | | Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not change. 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.

* [SCSI] zfcp: remove union zfcp_req_data, use unit refcount for FCP commandsAndreas Herrmann2005-09-19
| | | | | | | | | | | o union zfcp_req_data removed o increment unit refcount when processing FCP commands (This fixes a theoretical race: When all scsi commands of a unit are aborted and the scsi_device is removed then the unit could be removed before all fsf_requests of that unit are completely processed.)

| | | | | | | | | | | | This patch fixes a severe problem with 2.6.13-rc7. Due to recent SCSI changes it is not possible to add any LUNs to the zfcp device driver anymore. With registration of remote ports this is fixed.

| | | | | | | | | | | From: Heiko Carstens <heiko.carstens@de.ibm.com> Fixes module parameter parsing for "device" parameter. The original module parameter was changed while parsing it.

* [SCSI] zfcp: fix bug during adapter shutdownAndreas Herrmann2005-06-13
| | | | | | | | | | | | | | Fixes a race between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check. During adapter shutdown it occurred that a request was cleaned up twice. First during its normal completion. Second when dismiss_all was called. The fix is to serialize access to fsf request list between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check and delete a fsf request from the list if its completion is triggered. (Additionally a rwlock was replaced by a spinlock and fsf_req_cleanup was eliminated.)

* [SCSI] zfcp: fix: problem in send_els_handler when D_ID assignment changesAndreas Herrmann2005-06-13
| | | | | | | | | | | | | From: Maxim Shchetynin <maxim@de.ibm.com> Fixes a bug in zfcp_send_els_handler. If D_ID assignments for ports are changing between initiation of one ELS request and its completion the wrong port might be accessed in the completion for that ELS request. Thus a pointer to the port has to be passed for ELS requests to identify the port structure if required.

The old behaviour of allowing 6 retries with .5 seconds delay between retries was insufficient and qdio queues were shut down too erarly.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
