Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (21 commits) [SCSI] sd: fix computation of the full size of the device [SCSI] lib: string_get_size(): don't hang on zero; no decimals on exact [SCSI] sun3x_esp: Convert && to || [SCSI] sd: remove command-size switching code [SCSI] 3w-9xxx: remove unnecessary local_irq_save/restore for scsi sg copy API [SCSI] 3w-xxxx: remove unnecessary local_irq_save/restore for scsi sg copy API [SCSI] fix netlink kernel-doc [SCSI] sd: Fix handling of NO_SENSE check condition [SCSI] export busy state via q->lld_busy_fn() [SCSI] refactor sdev/starget/shost busy checking [SCSI] mptfusion: Increase scsi-timeouts, similariy to the LSI 4.x driver. [SCSI] aic7xxx: Take the LED out of diagnostic mode on PM resume [SCSI] aic79xx: user visible misuse wrong SI units (not disk size!) [SCSI] ipr: use memory_read_from_buffer() [SCSI] aic79xx: fix shadowed variables [SCSI] aic79xx: fix shadowed variables, add statics [SCSI] aic7xxx: update *_shipped files [SCSI] aic7xxx: update .reg files [SCSI] aic7xxx: introduce "dont_generate_debug_code" keyword in aicasm parser [SCSI] scsi_dh: Initialize path state to be passive when path is not owned ...
