Subject: [RFC 19/32] fs/fat: convert to struct inode_time
Date: Fri, 30 May 2014 22:01:43 +0200 [thread overview]
Message-ID: <1401480116-1973111-20-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1401480116-1973111-1-git-send-email-arnd@arndb.de>
fat uses 7-bit year numbers for inode timestamps, which will work
for the next 93 years, but the VFS uses struct timespec for timestamps,
which is only good until 2038 on 32-bit CPUs.
This gets us one small step closer to lifting the VFS limit by using
struct inode_time in fat.
