Synopsis: [geom] [patch] BIO_FLUSH not recorded by devstats State-Changed-From-To: open->feedback State-Changed-By: brueffer State-Changed-When: Wed Feb 5 18:11:49 CET 2014 State-Changed-Why: Hi Matt, I debated this change with mav@ and we were wondering what your specific use for this change is. While an adapted version (https://people.freebsd.org/~brueffer/geom_devstat.diff) of this patch works, the upstream userland tools have no special handling for BIO_FLUSH events. They end up in the _OTHER categories of libdevstat(3), which e.g. gstat does not show at all. Could you elaborate? http://www.freebsd.org/cgi/query-pr.cgi?pr=176744
