Module Name: src
Committed By: maxv
Date: Fri Feb 9 09:07:13 UTC 2018
Modified Files:
src/sys/uvm: uvm_bio.c
Log Message:
Use UVM_PROT_RW instead of UVM_PROT_ALL. This doesn't change anything,
since the protection code is not applied: the pages are manually kentered
as RW.
But fix it anyway, so that "pmap 0" does not say the map is executable.
