As originally reported by Jia-Ju, iscsit_tpg_enable_portal_group() holds iscsi_portal_group->tpg_state_lock while updating AUTHMETHOD via iscsi_update_param_value(), which performs a GFP_KERNEL allocation. However, since iscsit_tpg_enable_portal_group() is already protected by iscsit_get_tpg() -> iscsi_portal_group->tpg_access_lock in it's parent caller, ->tpg_state_lock only needs to be held when setting TPG_STATE_ACTIVE.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
