loli10K c44a3ec059 zvol: allow rename of in use ZVOL dataset ... While ZFS allow renaming of in use ZVOLs at the DSL level without issues the ZVOL layer does not correctly update the renamed dataset if the device node is open (zv->zv_open_count > 0): trying to access the stale dataset name, for instance during a zfs receive, will cause the following failure: VERIFY3(zv->zv_objset->os_dsl_dataset->ds_owner == zv) failed ((null) == ffff8800dbb6fc00) PANIC at zvol.c:1255:zvol_resume() Showing stack for process 1390 CPU: 0 PID: 1390 Comm: zfs Tainted: P O 3.16.0-4-amd64 #1 Debian 3.16.51-3 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 0000000000000000 ffffffff8151ea00 ffffffffa0758a80 ffff88028aefba30 ffffffffa0417219 ffff880037179220 ffffffff00000030 ffff88028aefba40 ffff88028aefb9e0 2833594649524556 6f5f767a3e2d767a 6f3e2d7465736a62 Call Trace: [<0>] ? dump_stack+0x5d/0x78 [<0>] ? spl_panic+0xc9/0x110 [spl] [<0>] ? mutex_lock+0xe/0x2a [<0>] ? zfs_refcount_remove_many+0x1ad/0x250 [zfs] [<0>] ? rrw_exit+0xc8/0x2e0 [zfs] [<0>] ? mutex_lock+0xe/0x2a [<0>] ? dmu_objset_from_ds+0x9a/0x250 [zfs] [<0>] ? dmu_objset_hold_flags+0x71/0xc0 [zfs] [<0>] ? zvol_resume+0x178/0x280 [zfs] [<0>] ? zfs_ioc_recv_impl+0x88b/0xf80 [zfs] [<0>] ? zfs_refcount_remove_many+0x1ad/0x250 [zfs] [<0>] ? zfs_ioc_recv+0x1c2/0x2a0 [zfs] [<0>] ? dmu_buf_get_user+0x13/0x20 [zfs] [<0>] ? __alloc_pages_nodemask+0x166/0xb50 [<0>] ? zfsdev_ioctl+0x896/0x9c0 [zfs] [<0>] ? handle_mm_fault+0x464/0x1140 [<0>] ? do_vfs_ioctl+0x2cf/0x4b0 [<0>] ? __do_page_fault+0x177/0x410 [<0>] ?
