| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free. While at it: - Add missing KERN_CONTs in it821x.c. - Use ATA_ID_WORDS and ATA_ID_*_LEN defines. - Remove unnecessary checks for drive->id. - s/drive_table/table/ in ide_in_drive_list(). - Cleanup ide_config_drive_speed() a bit. - s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave(). v2: Fix typo in drivers/ide/ppc/pmac.c.

This field is not actually referenced from kernel space at all, but is added for completeness and due to the userland tools which get their on-disk structure information from the gfs2_ondisk.h header file. Since we have to be backwards compatible, we will assume that any GFS2 sb for which the UUID is all 0 does not have a UUID as such. We should then be (after some userland changes) able to support the -U mount option. This addresses Fedora bugzilla #242689 Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| * | | | | [SCSI] fc_transport: Add an API to allow an LLD to create vportsAndrew Vasquez2008-10-03

This patch adds a symmetric call to the API to allow an NPIV-capable LLD to instantiate vports sans user intervention. Additional comments/updates: Re: scsi_fc_transport.txt Add a function prototype for fc_vport_terminate similar to what's done for fc_vport_create Re: fc_vport_create I recommend we pass the channel number in fc_vport_create rather than fixing it at zero. Also, ids->vport_type should be set to FC_PORTTYPE_NPIV prior to calling fc_vport_create. The comment is also meaningless.

| * | | | | [SCSI] lib: add generic helper to print sizes rounded to the correct SI rangeJames Bottomley2008-10-03

It rounds up to three significant figures and can be used for either memory or storage capacities. Oh, and I'm fully aware that 64 bits is only 16EiB ... the Zetta and Yotta units are added for future proofing against the day we have 128 bit computers ...

| * | | | | [SCSI] Update the SCSI state model to allow blocking in the created stateJames Bottomley2008-10-03

Fix this by adding a new state: CREATED_BLOCK which can only transition back to CREATED and disallow the CREATED -> BLOCK transition. Now both the created and blocked states that the mid-layer recognises can include CREATED_BLOCK. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

It is a reimplementation of the patch posted last week by David Somayajulu. http://marc.info/?l=linux-scsi&m=121745486221819&w=2 There are a few things done differently: - Transport support is included - Event delivery is included - The vendor message is now its own unique message type, considered part of the generic "SCSI Transport". - LLDD entry points are now registered rather than included in the scsi_host_template. Background: When I started to implement the event handler via template, I had to either: muck up scsi_add_host and scsi_remove_host; or have the event handler search all possible shosts. Neither was acceptable. Moving to a registration solves this, and also limits the scope of the changes to something that could be backported to a distro without breaking an already-released-distro kabi. However, I admit it isn't as elegant, as the passing of the LLDD host template in the registration and the complexity around dynamic add/remove shows. - The receive path was augmented to require a unique identifier for the LLDD before the message was allowed to be handed off to the driver. Given how quickly very fatal errors occur if there's msg mismatches (which I saw in testing my own tools :), I believe this to be a very good thing. The id plays off the vendor id scheme already introduced for the vendor unique event messages used by FC. Additionally, the id use as the basis of the registration/deregistration. - Send assist functions, for both the transport and LLDDs are included.
