https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221356 Bug ID: 221356 Summary: [patch] Improve swapon_check_swzone() function in swap_pager.c Product: Base System Version: 11.1-RELEASE Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: ota@j.email.ne.jp Keywords: patch Created attachment 185184 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D185184&action= =3Dedit Improve swapon_check_swzone() function Improve swapon_check_swzone() function. Change to more descriptive swapon_check_swzone() warnings. #1 Indicate half the size is recommended size. (I couldn't figure out and don't know why half is recommended, though.) #2 Advice when the swap device size exceeds the max size. Convert swap_pager_full to static variable as it is not used in global spac= e. Add a unit to swap_total description. Call uma_zone_get_max() to find proper swap_maxpages. Use swap_maxpages and other global variable in swapon_check_swzone(). Convert swapon_check_swzone() to a void function. Patch tested on 11.1-RELEASE and compiled on CURRENT of i386. How to test $ swapon <extra devices> until you exceed these 2 thresholds - half size and the max size. Easier to test on systems with less memory. --=20 You are receiving this mail because: You are the assignee for the bug.=
