Subject: [IPoIB] Improve ipoib_timeout() output
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4b2d319b53810ab00ef3d8fdfc1c1ab0647ab0a7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[IPoIB] Improve ipoib_timeout() output

Use jiffies_to_msecs() so we print a human-readable time so
we don't have to worry about what HZ is configured to, and
print out a few values to make post-mortem analysis easier.
