Subject: dlm: fix rcom_names message to self
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=599e0f584de8ff16b1428e2e16118757619f1d1b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dlm: fix rcom_names message to self

The recent patch to validate data lengths in rcom_names messages
failed to account for fake messages a node directs to itself before
ever sending it.  In this case we need to fill in the message length
in the header for the validation code to use.
