fs/sysv/inode.c: use ktime_get_real_seconds() for superblock stamp 2018-08-22T17:52:51+00:00 Arnd Bergmann arnd@arndb.de 2018-08-22T05:01:13+00:00 3e811f053aec66e8a6d2a0ee3d031e7c988e3d15 get_seconds() is deprecated in favor of ktime_get_real_seconds(), which returns a 64-bit timestamp. In the SYSV file system, the superblock timestamp is only 32 bits wide, and it is used to check whether a file system is clean, so the best solution seems to be to force a wraparound and explicitly convert it to an unsigned 32-bit value. This is independent of the inode timestamps that are also 32-bit wide on disk and that come from current_time().
