Subject: Revert "iscsi-target: Avoid IN_LOGOUT failure case for iser-target"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2a03ee8c5677acd7ab61b0be7b880b3d3de1bcf2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Revert "iscsi-target: Avoid IN_LOGOUT failure case for iser-target"

This reverts commit 72859d91d93319c00a18c29f577e56bf73a8654a.

The original patch was wrong, iscsit_close_connection() still needs
to release iscsi_conn during both normal + exception IN_LOGOUT status
with ib_isert enabled.

The original OOPs is due to completing conn_logout_comp early within
iscsit_close_connection(), causing isert_wait4logout() to complete
instead of waiting for iscsit_logout_post_handler_*() to be called.
