Modified files:
sys/kern sys_process.c
Log:
Use VM_FAULT_DIRTY to fault in pages for write access in
proc_rwmen.
Otherwise copy on write may create an anonymous page that is
not marked as dirty. Since writing data to these pages
in this function also does not dirty these pages they may be
later discarded by the pagedaemon.
