If anyone has any objections, please let me know. ------------------ From: Namjae Jeon commit 146c3fc6540e24eef6296395a35bf5b924182e8b upstream. With CONFIG_HZ=1024, msecs_to_jiffies(1200) includes an overflow check that calls jiffies_to_msecs(MAX_JIFFY_OFFSET). Its saturation branch returns MAX_JIFFY_OFFSET, which exceeds the six-second upper bound. GCC 10.5 carries that branch into clamp_t()'s bounds check and fails to build ksmbd_tcp_writev() on MIPS. Compute the 1200 ms lower bound with DIV_ROUND_UP() instead, so both bounds are compile-time constants. The lower bound still rounds up to the next jiffy, and the retry interval remains between 1.2 and 6 seconds.
