Subject: Drivers: hv: vmbus: Reduce the delay between retries in vmbus_post_msg()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8de0d7e951826d7592e0ba1da655b175c4aa0923;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Drivers: hv: vmbus: Reduce the delay between retries in vmbus_post_msg()

The current delay between retries is unnecessarily high and is negatively
affecting the time it takes to boot the system.
