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
