[PATCH 1/2] xfs: change the prefix of XFS_EOF_FLAGS_* to XFS_ICWALK_FLAG_

From: "Darrick J. Wong" <djwong@kernel.org>
Date: 2021-06-03 03:13:01
Subsystem: filesystems (vfs and infrastructure), the rest, xfs filesystem · Maintainers: Alexander Viro, Christian Brauner, Linus Torvalds, Carlos Maiolino 

From: Darrick J. Wong <djwong@kernel.org>

In preparation for renaming struct xfs_eofblocks to struct xfs_icwalk,
change the prefix of the existing XFS_EOF_FLAGS_* flags to
XFS_ICWALK_FLAG_ and convert all the existing users.  This adds a degree
of interface separation between the ioctl definitions and the incore
parameters.

Signed-off-by: Darrick J. Wong <djwong@kernel.org>
