ata: Convert ata__printk(KERN_ to ata__

2011-07-23T21:57:36+00:00

Saves text by removing nearly duplicated text format strings by
creating ata__printk functions and printf extension %pV.

ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB)

Format string duplication comes from:

 #define ata_link_printk(link, lv, fmt, args...) do { \
       if (sata_pmp_attached((link)->ap) || (link)->ap->slave_link)    \
               printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id,   \
                      (link)->pmp , ##args); \
       else \
               printk("%sata%u: "fmt, lv, (link)->ap->print_id , ##args); \
       } while(0)

Coalesce long formats.

ata: Convert dev_printk(KERN_ to dev_(

2011-07-23T21:57:36+00:00

Saves a bit of text as the call takes fewer args.

Coalesce a few formats.
Convert a few bare printks to pr_cont.

libata-sff: prevent irq descriptions for dummy ports

2011-05-14T18:59:54+00:00

This is a cosmetic change to prevent libata-sff adding irq
descriptions to dummy ports, since the information, while largely
unused, is erroneous.

libata-sff: fix HSM_ST_ERR handling in __ata_sff_port_intr()

2010-12-24T18:32:07+00:00

While separating out BMDMA irq handler from SFF, commit c3b28894
(libata-sff: separate out BMDMA irq handler) incorrectly made
__ata_sff_port_intr() consider an IRQ to be an idle one if the host
state was transitioned to HSM_ST_ERR by ata_bmdma_port_intr().

This makes BMDMA drivers ignore IRQs reporting host bus error which
leads to timeouts instead of triggering EH immediately.  Fix it by
making __ata_sff_port_intr() consider the IRQ to be an idle one iff
the state is HSM_ST_IDLE.  This is equivalent to adding HSM_ST_ERR to
the "break"ing case but less error-prone.

workqueue: convert cancel_rearming_delayed_work[queue]() users to cancel_delayed_work_sync()

2010-12-15T09:56:11+00:00

cancel_rearming_delayed_work[queue]() has been superceded by
cancel_delayed_work_sync() quite some time ago.  Convert all the
in-kernel users.  The conversions are completely equivalent and
trivial.
