Dan Williams a455aa72f7 device-dax/kmem: fix resource release ... The conversion to request_mem_region() is broken because it assumes that the range is marked busy prior to release. However, due to the way that the kmem driver manipulates the IORESOURCE_BUSY flag (clears it to let {add,remove}_memory() handle busy) it requires a manual release_resource() to perform cleanup. Given that the actual 'struct resource *' needs to be recalled, not just the range, add that tracking to the kmem driver-data. Fixes: 0513bd5bb1 ("device-dax/kmem: replace release_resource() with release_mem_region()") Reported-by: David Hildenbrand <david@redhat.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: David Hildenbrand <david@redhat.com> Cc: Vishal Verma <vishal.l.verma@intel.com> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Pavel Tatashin <pasha.tatashin@soleen.com> Cc: Brice Goglin <Brice.Goglin@inria.fr> Cc: Dave Jiang <dave.jiang@intel.com> Cc: Ira Weiny <ira.weiny@intel.com> Cc: Jia He <justin.he@arm.com> Cc: Joao Martins <joao.m.martins@oracle.com> Cc: Jonathan Cameron <Jonathan.Cameron@huawei.com> Link: https://lkml.kernel.org/r/160272252925.3136502.17220638073995895400.stgit@dwillia2-desk3.amr.corp.intel.com Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2020-10-16 11:11:14 -07:00
