From 2a0ec1d9ed7f3aa7974fccfbb612fadda2e10bad Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 23 Apr 2012 15:59:02 +1000 Subject: xfs: move xfs_get_extsz_hint() and kill xfs_rw.h The only thing left in xfs_rw.h is a function prototype for an inode function. Move that to xfs_inode.h, and kill xfs_rw.h. Also move the function implementing the prototype from xfs_rw.c to xfs_inode.c so we only have one function left in xfs_rw.c Signed-off-by: Dave Chinner Reviewed-by: Mark Tinguely Reviewed-by: Christoph Hellwig Signed-off-by: Ben Myers --- fs/xfs/xfs_inode.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'fs/xfs/xfs_inode.c') diff --git a/fs/xfs/xfs_inode.c b/fs/xfs/xfs_inode.c index f64b482a7953..c6fb5f0577b8 100644 --- a/fs/xfs/xfs_inode.c +++ b/fs/xfs/xfs_inode.c @@ -61,6 +61,20 @@ STATIC int xfs_iformat_local(xfs_inode_t *, xfs_dinode_t *, int, int); STATIC int xfs_iformat_extents(xfs_inode_t *, xfs_dinode_t *, int); STATIC int xfs_iformat_btree(xfs_inode_t *, xfs_dinode_t *, int); +/* + * helper function to extract extent size hint from inode + */ +xfs_extlen_t +xfs_get_extsz_hint( + struct xfs_inode *ip) +{ + if ((ip->i_d.di_flags & XFS_DIFLAG_EXTSIZE) && ip->i_d.di_extsize) + return ip->i_d.di_extsize; + if (XFS_IS_REALTIME_INODE(ip)) + return ip->i_mount->m_sb.sb_rextsize; + return 0; +} + #ifdef DEBUG /* * Make sure that the extents in the given memory buffer -- cgit v1.2.3
