| |
Hello, Jens.
I hope you had fun on your vacation and at OLS. I'm posting 18 welcome-back patches today. :-p This mail is to show the overview of the patches. All patches are against master head of linux-2.6-block tree.
patch #1 : fix-elevator_find. remove try_module_get race in elevator_find. patch #2 : fix-cfq_find_next_crq. fix cfq_find_next_crq bug in cfq. patch #3-7 : generic dispatch queue patchset. implements generic dispatch queue. patch #8 : reimplement-elevator-switch. reimplements elevator switch using generic dispatch queue. draining isn't needed anymore. patch #9-#18 : ordered reimplementation patchset. reimplements I/O barrier handling.
Both generic dispatch queue patchset and ordered reimplementation patchset were previously posted. They are reordered (as you asked) and I've added missing bits (all elevators are updated, docs are updated). Also, there were a few changes and fixes. I'll mention them when I post those patches.
I've tested these changes by running parallelly...
* random raw read (concurrency 8) * repeatedly mounting a ext3 fs with -o barrier=1, copying, syncing & checksumming a 128M file, and unmounting the fs. * periodic scheduler switch (each iosched runs for 3 minutes and then switched to the next one)
This test has been running for several hours without a problem and I will keep it running for today and maybe tomorrow unless I have to use the test machine for some other purpose.
Thanks.
