Comment 1 IBM Bug Proxy 2008-09-22 05:30:22 EDT
Hi Emily,

the component should be blktrace:

IBM System z Developers have done 2 patches will are in progress for upstream
for blktrace, so till then, IBM will attach these patches to this Bugzilla so
that Red Hat applies them to the current blktrace version.

Thank you,
Gonzalo Muelas.
Comment 2 IBM Bug Proxy 2008-09-22 11:40:50 EDT
Hi Gonzalo, there is no blktrace component. I'll move this to distribution for
now as a new package request. Emily

No attachments so far?  (see comment #1)

If they're upstream, pointers to the git commits would be fine.

Note also that blktrace is in EPEL for RHEL5 already.  I'd be happy to be sure the patches IBM needs make it to the EPEL package for now, as well (once they are upstream).

The code for this feature is upstream accepted with blktrace 1.0.0

When RHEL 6 takes blktrace 1.0.0 or higher this feature is fulfilled

------- Comment From mgrf@de.ibm.com 2009-05-06 07:12 EDT-------
Hello Red Hat,

We recognized that the upstream revision level of blktrace did not change after accepted commits made it into blktrace.

To ensure the level of blktrace (1.0.0) and commits get included into RHEL 6 that are required to fulfill this feature request
here a list of required commits for reference:

Here's info on the blktrace version needed:
blktrace 1.0.0 with all patches up to January 22, which is (git commit ids):
(end of patches up to January 22)

(Tom Zanussi fix for race that bit us)

(Martin's latest two patches)
Comment 11 Siddharth Nagar 2009-05-29 14:04:39 EDT
This is completed upstream and will be included in 6.0
