Subject: [PATCH V5 11/12] fs/xfs: Remove xfs_diflags_to_linux()
Date: Wed, 26 Feb 2020 21:24:41 -0800	[thread overview]
Message-ID: <20200227052442.22524-12-ira.weiny@intel.com> (raw)
In-Reply-To: <20200227052442.22524-1-ira.weiny@intel.com>

From: Ira Weiny <ira.weiny@intel.com>

The functionality in xfs_diflags_to_linux() is now identical to
xfs_diflags_to_iflags().

Remove xfs_diflags_to_linux() and call xfs_diflags_to_iflags() directly.

While we are here simplify xfs_diflags_to_iflags() to take just struct
xfs_inode.

And use xfs_ip2xflags() to ensure future diflags are included correctly.

Changes from V4:
	Pick up lkp build suggestion (make xfs_inode_enable_dax() static)
