Merge branch 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo: - libata has always been limiting the maximum queue depth to 31, with one entry set aside mostly for historical reasons. This didn't use to make much difference but Jens found out that modern hard drives can actually perform measurably better with the extra one queue depth. Jens updated libata core so that it can make use of full 32 queue depth - Damien updated command retry logic in error handling so that it doesn't unnecessarily retry when upper layer (SCSI) is gonna handle them - A couple misc changes * 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: sata_fsl: use the right type for tag bitshift ahci: enable full queue depth of 32 libata: don't clamp queue depth to ATA_MAX_QUEUE - 1 libata: add extra internal command sata_nv: set host can_queue count appropriately libata: remove assumption that ATA_MAX_QUEUE - 1 is the max libata: use ata_tag_internal() consistently libata: bump ->qc_active to a 64-bit type libata: convert core and drivers to ->hw_tag usage libata: introduce notion of separate hardware tags libata: Fix command retry decision libata: Honor RQF_QUIET flag libata: Make ata_dev_set_mode() less verbose libata: Fix ata_err_string() libata: Fix comment typo in ata_eh_analyze_tf() sata_nv: don't use block layer bounce buffer ata: hpt37x: Convert to use match_string() helper
