Re: [Y2038] [PATCH] ata: fix "ering" sysfs time printing

The sysfs file for the libata error handling has multiple issues in the way it prints time stamps:

• it prints a 9-digit nanosecond value using a %06lu format string, which drops some leading zeroes
• it converts a 64-bit jiffes value to a timespec using jiffies_to_timespec(), which takes a 'long' argument, so the result is wrong after a jiffies overflow (49 days).
• we try to avoid using timespec because that generally overflows in 2038, although this particular usage is ok.

This replaces the jiffies_to_timespec call with an open-coded implementation that gets it right.

Heh, I'm not even sure why we're exposing this but it's already there. Applied to libata/for-4.8.

Thanks!
