The current fcloop driver gets its lport structure from the private area co-allocated with the fc_localport. All is fine except the teardown path, which wants to wait on the completion, which is marked complete by the delete_localport callback performed after unregister_localport. The issue is, the nvme_fc transport frees the localport structure immediately after delete_localport is called, meaning the original routine is trying to wait on a complete that was just freed. Change such that a lport struct is allocated coincident with the addition and registration of a localport. The private area of the localport now contains just a backpointer to the real lport struct. Now, the completion can be waited for, and after completing, the new structure can be kfree'd. Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Christoph Hellwig <hch@lst.de> |
