From: Mike Christie <michael.christie@oracle.com> mainline inclusion from mainline-v5.12-rc1 commit c435f0a9ecb7435e70f447b7231ca52de589b252 category: bugfix issue: #I3ZXZF CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ----------------------------------------------- We allocate the iSCSI host workq in iscsi_host_alloc() so iscsi_host_free() should do the destruction. Drivers can then do their error/goto handling and call iscsi_host_free() to clean up what has been allocated in iscsi_host_alloc().
