From f13fae2d2a9372a5155d20bc9da4c14f02193277 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 21 Jul 2008 16:16:15 +1000 Subject: [XFS] Remove vn_revalidate calls in xfs. These days most of the attributes in struct inode are properly kept in sync by XFS. This patch removes the need for vn_revalidate completely by: - keeping inode.i_flags uptodate after any flags are updated in xfs_ioctl_setattr - keeping i_mode, i_uid and i_gid uptodate in xfs_setattr SGI-PV: 984566 SGI-Modid: xfs-linux-melb:xfs-kern:31679a Signed-off-by: Christoph Hellwig Signed-off-by: Tim Shimmin Signed-off-by: Lachlan McIlroy --- fs/xfs/linux-2.6/xfs_ioctl.c | 29 +++++++++++++++++++++++++++-- 1 file changed, 27 insertions(+), 2 deletions(-) (limited to 'fs/xfs/linux-2.6/xfs_ioctl.c') diff --git a/fs/xfs/linux-2.6/xfs_ioctl.c b/fs/xfs/linux-2.6/xfs_ioctl.c index d1b0da6bcdca..acb978d9d085 100644 --- a/fs/xfs/linux-2.6/xfs_ioctl.c +++ b/fs/xfs/linux-2.6/xfs_ioctl.c @@ -923,6 +923,30 @@ xfs_set_diflags( ip->i_d.di_flags = di_flags; } +STATIC void +xfs_diflags_to_linux( + struct xfs_inode *ip) +{ + struct inode *inode = XFS_ITOV(ip); + unsigned int xflags = xfs_ip2xflags(ip); + + if (xflags & XFS_XFLAG_IMMUTABLE) + inode->i_flags |= S_IMMUTABLE; + else + inode->i_flags &= ~S_IMMUTABLE; + if (xflags & XFS_XFLAG_APPEND) + inode->i_flags |= S_APPEND; + else + inode->i_flags &= ~S_APPEND; + if (xflags & XFS_XFLAG_SYNC) + inode->i_flags |= S_SYNC; + else + inode->i_flags &= ~S_SYNC; + if (xflags & XFS_XFLAG_NOATIME) + inode->i_flags |= S_NOATIME; + else + inode->i_flags &= ~S_NOATIME; +} #define FSX_PROJID 1 #define FSX_EXTSIZE 2 @@ -1121,8 +1145,10 @@ xfs_ioctl_setattr( if (mask & FSX_EXTSIZE) ip->i_d.di_extsize = fa->fsx_extsize >> mp->m_sb.sb_blocklog; - if (mask & FSX_XFLAGS) + if (mask & FSX_XFLAGS) { xfs_set_diflags(ip, fa->fsx_xflags); + xfs_diflags_to_linux(ip); + } xfs_trans_log_inode(tp, ip, XFS_ILOG_CORE); xfs_ichgtime(ip, XFS_ICHGTIME_CHG); @@ -1160,7 +1186,6 @@ xfs_ioctl_setattr( (mask & FSX_NONBLOCK) ?
