[Qemu-devel] [PATCH v3 00/21] Extended I/O accounting |
Date: |
Thu, 22 Oct 2015 11:11:10 +0300 |
Here's a new version of the extended I/O accounting patches.
This one is rebased on top of the current master, has a few minor
documentation fixes and drops the 'supports_stats' field completely.
Regards,
Berto
v3:
- Rebased on top of the current master and on Max's BlockBackend
series v7
- patch 4: minor documentation fixes
- patch 5: s/miliseconds/nanoseconds/
- patch 6: dropped, there's no "supports_stats" anymore
- patch 7 (now 6): explain why block_acct_invalid() does not update
total_time_ns[]
- patch 12 (now 11): don't initialize BlockAcctCookie to { 0 }, it's
not needed
v2: https://lists.gnu.org/archive/html/qemu-block/2015-10/msg00161.html
- First complete implementation of the new statistics
v1: https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg03321.html
- Initial series containing only the timed average infrastructure.
