Merge patch series "scsi: fixes for targets with many LUNs, and scsi_target_block rework"
Martin Wilck <mwilck@suse.com> says:
This patch series addresses some issues we saw in a test setup with a
large number of SCSI LUNs. The first two patches simply increase the
number of available sg and bsg devices. 3-5 fix a large delay we
encountered between blocking a Fibre Channel remote port and the
dev_loss_tmo. 6 renames scsi_target_block() to scsi_block_targets(),
and makes additional changes to this API, as suggested in the review
of the v2 series. 7 improves a warning message.
