[PATCH 0/3] xen/blkback: several fixes of resource management

Show all headers | View raw

Destroying a Xen guest domain while it was doing I/Os via xen-blkback
leaked several resources, including references of the guest's memory
pages.

This patch series addresses those leaks by correcting usage of
reference counts and the sequence when to free which resource.

The series applies on top of commit 2d4456c73a487abe ("block:
xen-blkback: add null check to avoid null pointer dereference") in
Jens Axboe's tree kernel/git/axboe/linux-block.git

Juergen Gross (3):
  xen/blkback: fix disconnect while I/Os in flight
  xen/blkback: don't free be structure too early
  xen/blkback: don't use xen_blkif_get() in xen-blkback kthread
