| | | | | | | | | | | | | | maps onto the upages. We used to use this extensively, particularly for ps and gdb. Both of these have been "fixed". ps gets the p_stats via eproc along with all the other stats, and gdb uses the regs, fpregs etc files. Once apon a time the UPAGES were mapped here, but that changed back in January '96. This essentially kills my revisions 1.16 and 1.17. The 2-page "hole" above the stack can be reclaimed now.

* Collect read and write counts for filesystems. This new codeKirk McKusick1999-12-011-0/+21
| | | | | | | | | | | | | | | | | drops the counting in bwrite and puts it all in spec_strategy. I did some tests and verified that the counts collected for writes in spec_strategy is identical to the counts that we previously collected in bwrite. We now also get read counts (async reads come from requests for read-ahead blocks). Note that you need to compile a new version of mount to get the read counts printed out. The old mount binary is completely compatible, the only reason to install a new mount is to get the read counts printed.

(Other than having the debugger automatically access the symbols for a process, the main use I'd found was with some minor accounting ability, but _that_ depends on it being in the filesystem space; an ioctl access method would be useless in that case.)
