PR/55702 CVS commit: src/sys

The following reply was made to PR kern/55702; it has been noted by GNATS.

From: "Chuck Silvers" <>
Subject: PR/55702 CVS commit: src/sys
Date: Sun, 18 Oct 2020 18:22:29 +0000

 Module Name:	src
 Committed By:	chs
 Date:		Sun Oct 18 18:22:29 UTC 2020
 Modified Files:
 	src/sys/rump/librump/rumpvfs: vm_vfs.c
 	src/sys/uvm: uvm_page.c uvm_pager.c
 Log Message:
 Move the handling of PG_PAGEOUT from uvm_aio_aiodone_pages() to
 uvm_page_unbusy() so that all callers of uvm_page_unbusy() don't need to
 handle this flag separately.  Split out the pages part of uvm_aio_aiodone()
 into uvm_aio_aiodone_pages() in rump just like in the real kernel.
 In ZFS functions that can fail to copy data between the ARC and VM pages,
 use uvm_aio_aiodone_pages() rather than uvm_page_unbusy() so that we can
 handle these "I/O" errors.  Fixes PR 55702.
