  "message": "libata: beef up iterators\n\nThere currently are the following looping constructs.\n\n* __ata_port_for_each_link() for all available links\n* ata_port_for_each_link() for edge links\n* ata_link_for_each_dev() for all devices\n* ata_link_for_each_dev_reverse() for all devices in reverse order\n\nNow there\u0027s a need for looping construct which is similar to\n__ata_port_for_each_link() but iterates over PMP links before the host\nlink.  Instead of adding another one with long name, do the following\ncleanup.\n\n* Implement and export ata_link_next() and ata_dev_next() which take\n  @mode parameter and can be used to build custom loop.\n* Implement ata_for_each_link() and ata_for_each_dev() which take\n  looping mode explicitly.\n\nThe following iteration modes are implemented.\n\n* ATA_LITER_EDGE\t\t: loop over edge links\n* ATA_LITER_HOST_FIRST\t\t: loop over all links, host link first\n* ATA_LITER_PMP_FIRST\t\t: loop over all links, PMP links first\n\n* ATA_DITER_ENABLED\t\t: loop over enabled devices\n* ATA_DITER_ENABLED_REVERSE\t: loop over enabled devices in reverse order\n* ATA_DITER_ALL\t\t\t: loop over all devices\n* ATA_DITER_ALL_REVERSE\t\t: loop over all devices in reverse order\n\nThis change removes exlicit device enabledness checks from many loops\nand makes it clear which ones are iterated over in which direction.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n",
