Subject: [PATCH 00 of 10] blkfront pvops updates
Date: Thu, 29 Apr 2010 02:19:37 -0000	[thread overview]
Message-ID: <patchbomb.1272507577@agari.van.xensource.com> (raw)


Hi.

Here are couple of bugfixes for blkfront.

 1. Bdev removal was slightly buggy. [Is nobody out there using
    block-detach??] Also it seems like we'be been leaking the gendisk
    structs for a long time.

 2. Fixes most common occasions where disk open/close races against
    backend state switches. This one didn't come for free:
	* xenbus_switch_state growing transactions again.
	* New mutex in blkfront_info
	* Bdev .open/.close rewritten accordingly.

Cheers,
Daniel
