CVS commit: src/sys/uvm

["Andrew Doran" <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Sat May 23 11:59:03 UTC 2020

Modified Files:
        src/sys/uvm: uvm_bio.c

Log Message:
- In ubc_alloc() take initial offset into account in the UBC_FAULTBUSY case
  or one too few pages can be mapped.

- In ubc_release() with UBC_FAULTBUSY, chances are that pages are newly
  allocated and freshly enqueued, so avoid uvm_pageactivate() if possible

- Keep track of the pages mapped in ubc_alloc() in an array on the stack,
  and use this to avoid calling pmap_extract() in ubc_release().
