Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull more SCSI updates from James Bottomley: "Mostly small bug fixes and small updates. The only things of note is a qla2xxx fix for crash on hotplug and timeout and the addition of a user exposed abstraction layer for persistent reservation error return handling (which necessitates the conversion of nvme.c as well as SCSI)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: qla2xxx: Fix crash when I/O abort times out nvme: Convert NVMe errors to PR errors scsi: sd: Convert SCSI errors to PR errors scsi: core: Rename status_byte to sg_status_byte block: Add error codes for common PR failures scsi: sd: sd_zbc: Trace zone append emulation scsi: libfc: Include the correct header
