In this case it is Tim Deegan (cc'ed) and the patch looks like a straightforward and obviously correct bug fix to me, as pretty clearly explained in the changeset comment. Perhaps it has revealed a latent bug elsewhere? The patch is also in 3.3.1 by the way. Have you seen problems there too? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
