Package: xosview
Version: 1.8.3+debian-11
Severity: wishlist
Tags: patch
I created a patch that adds memory fields for SLAB, mapped files, and page
tables. It's mainly for the SLAB field, since if the SLAB cache gets very
large (let's say 1/3 of the system's ram or more), users might either
think that their apps are taking up that amount of memory or that there
might be a kernel leak.
This patch will only work with 2.6 kernels that list the fields "Slab",
"Mapped", and "PageTables" in /proc/meminfo.
