2007-10-15scsi/gdth: fix crash in gdth_timeout if no gdth controllers foundLinus Torvalds1-0/+4
If the gdth module is loaded (or compiled in), the gdth_timeout function gets started even if no actual gdth controllers are found b the probing. That ends up not only being unnecessary, but also causes a crash due to the function blindly just trying to pick the first entry off the "gdth_instances" list, and accessing it - which obviously doesn't work if the list is empty!

2007-10-13Driver core: change add_uevent_var to use a structKay Sievers1-7/+2
This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

gdth_execute() will issue an internal, none scsi-standard commands onto __gdth_queuecommand(). Since it is not recommended to set struct scsi_cmnd IO members in llds, gdth now uses internal IO members for IO. In the case of gdth_execute() these members will be set properly. In case the command was issued from scsi-ml (by gdth_queuecommand) they will be set from scsi IO accessors. * define gdth IO accessors and use them throughout the driver. * use an sg-of-one in gdth_execute() and fix gdth_special_cmd() accordingly. * Clean the not use_sg code path and company Signed-off-by Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2007-10-12[SCSI] gdth: Setup proper per-command private dataBoaz Harrosh3-36/+91
- scsi_cmnd and specifically ->SCp of, where heavily abused with internal meaning members and flags. So introduce a new struct gdth_cmndinfo, put it on ->host_scribble and define a gdth_cmnd_priv() accessor to retrieve it from a scsi_cmnd. - The structure now holds two members: internal_command - replaces the IS_GDTH_INTERNAL_CMD() croft. sense_paddr - which was a 64-bit spanning on 2 32-bit members of SCp. More overloaded members from SCp and scsi_cmnd will be moved in a later patch (For easy review). - Split up gdth_queuecommand to an additional internal_function. The later is the one called by gdth_execute(). This will be more evident later in the scsi accessors patch, but it also facilitates in the differentiation between internal_command and external. And the setup of gdth_cmndinfo of each command. Signed-off-by Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

But the io_ctrl from user mode now suffers performance-wise because code has to do a sequential search for the requested host number.

2007-10-12libata-link: introduce ata_linkTejun Heo2-8/+8
Introduce ata_link. It abstracts PHY and sits between ata_port and ata_device. This new level of abstraction is necessary to support SATA Port Multiplier, which basically adds a bunch of links (PHYs) to a ATA host port. Fields related to command execution, spd_limit and EH are per-link and thus moved to ata_link. This patch only defines the host link. Multiple link handling will be added later. Also, a lot of ap->link derefences are added but many of them will be removed as each part is converted to deal directly with ata_link instead of ata_port. This patch introduces no behavior change.
