CVS commit: src/sys/dev/ata

Module Name:    src
Committed By:   thorpej
Date:           Sat Apr 25 00:07:27 UTC 2020

Modified Files:
        src/sys/dev/ata: ata.c ata_subr.c atavar.h

Log Message:
Rather than creating a kthread-per-channel, use a threadpool and a
threadpool-job-per-channel for the in-thread-context work that needs
to be done (which is rare).

On one of my test systems, this results in the total number of LWPs
after multi-user boot dropping from 116 to 78.
