Subject: [DLM] fix iovec length in recvmsg
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4c5e1b1a8c3f591b21f09001d6748296ddff33b8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[DLM] fix iovec length in recvmsg

The DLM always passes the iovec length as 1, this is wrong when the circular
buffer wraps round.
