Re: [Xen-devel] [PATCH v2] xen-blkback: defer freeing blkif to avoid blocking xenwatch

[Vasiliy Tolstov <v.tolstov@xxxxxxxxx>]

Sorry, but now i'm not understand - what patches are missed from stable 3.10.x ?
For example 
https://groups.google.com/forum/#!msg/linux.kernel/Ih9XKvJNGjI/RZ4huN4K4AQJ
does it included in 3.10.x?
