[PATCH 1/2] e2fsck: always fix invalid extra field in timestamps if time_t is 32-bits

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Systems with 32-bit time_t's can be used past 2038, so we should
always modify dates with extra_time=3.  (On systems with 64-bit
time_t's we will fix these dates before the year 2242.)
