In commitd72d827f2f, I used 'cpumask_t' incorrectly: void iscsit_thread_get_cpumask(struct iscsi_conn *conn) { int ord, cpu; cpumask_t conn_allowed_cpumask; ...... } static ssize_t lio_target_wwn_cpus_allowed_list_store( struct config_item *item, const char *page, size_t count) { int ret; char *orig; cpumask_t new_allowed_cpumask; ...... } The correct pattern should be as follows: cpumask_var_t mask; if (!zalloc_cpumask_var(&mask, GFP_KERNEL)) return -ENOMEM; ... use 'mask' here ... free_cpumask_var(mask); Link: https://lore.kernel.org/r/20220516054721.1548-1-mingzhe.zou@easystack.cn Fixes:d72d827f2f("scsi: target: Add iscsi/cpus_allowed_list in configfs") Reported-by: Test Bot <zgrieee@gmail.com> Reviewed-by: Mike Christie <michael.christie@oracle.com> Signed-off-by: Mingzhe Zou <mingzhe.zou@easystack.cn> Signed-off-by: Martin K.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
