Dan Williams 06282373ff mm/memremap: Fix reuse of pgmap instances with internal references ... Currently, attempts to shutdown and re-enable a device-dax instance trigger: Missing reference count teardown definition WARNING: CPU: 37 PID: 1608 at mm/memremap.c:211 devm_memremap_pages+0x234/0x850 [..] RIP: 0010:devm_memremap_pages+0x234/0x850 [..] Call Trace: dev_dax_probe+0x66/0x190 [device_dax] really_probe+0xef/0x390 driver_probe_device+0xb4/0x100 device_driver_attach+0x4f/0x60 Given that the setup path initializes pgmap->ref, arrange for it to be also torn down so devm_memremap_pages() is ready to be called again and not be mistaken for the 3rd-party per-cpu-ref case. Fixes: 24917f6b10 ("memremap: provide an optional internal refcount in struct dev_pagemap") Reported-by: Fan Du <fan.du@intel.com> Tested-by: Vishal Verma <vishal.l.verma@intel.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Christoph Hellwig <hch@lst.de> Cc: Ira Weiny <ira.weiny@intel.com> Cc: Jason Gunthorpe <jgg@mellanox.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/156530042781.2068700.8733813683117819799.stgit@dwillia2-desk3.amr.corp.intel.com Signed-off-by: Dan Williams <dan.j.williams@intel.com>		2019-08-09 14:16:15 -07:00
