Subject: nvmet: for nvme admin set_features cmd, call nvmet_check_data_len_lte()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ddf91717693f1ac524329a88f86ab09e66b18cbe;p=linux.git

nvmet: for nvme admin set_features cmd, call nvmet_check_data_len_lte()

This is due to the fact that the host is allowed to pass the controller
an sgl describing a buffer that is larger than the payload itself
