Subject: [RFC 32/32] fs: use new inode_time definition unconditionally
Date: Fri, 30 May 2014 22:01:56 +0200 [thread overview]
Message-ID: <1401480116-1973111-33-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1401480116-1973111-1-git-send-email-arnd@arndb.de>
After all file systems have been converted to use 'struct inode_time'
for timestamps, we can remove the compatibility definition for this
structure.
This patch picks the first of the three variants I defined, but we
could pick one of the others as well.
