From 61436febae29085bffc7c291db03cbd709dc68a3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 20 May 2008 11:30:46 +1000 Subject: [XFS] kill xfs_igrow_start and xfs_igrow_finish xfs_igrow_start just expands to xfs_zero_eof with two asserts that are useless in the context of the only caller and some rather confusing comments. xfs_igrow_finish is just a few lines of code decorated again with useless asserts and confusing comments. Just kill those two and merge them into xfs_setattr.

To avoid polluting the dcache, we implement a new directory inode operations for lookup. xfs_vn_ci_lookup() stores the correct case name in the dcache. The "actual name" is only allocated and returned for a case- insensitive match and not an actual match. Another unusual interaction with the dcache is not storing negative dentries like other filesystems doing a d_add(dentry, NULL) when an ENOENT is returned. During the VFS lookup, if a dentry returned has no inode, dput is called and ENOENT is returned. By not doing a d_add, this actually removes it completely from the dcache to be reused. create/rename have to be modified to support unhashed dentries being passed in.

Also rename the ATTR_ flags to XFS_ATTR_ to not conflict with the ATTR_ flags used by the VFS.

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/xfs_vnodeops.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'fs/xfs/xfs_vnodeops.c') diff --git a/fs/xfs/xfs_vnodeops.c b/fs/xfs/xfs_vnodeops.c index b792a121b1a7..76a1166af822 100644 --- a/fs/xfs/xfs_vnodeops.c +++ b/fs/xfs/xfs_vnodeops.c @@ -83,6 +83,7 @@ xfs_setattr( cred_t *credp) { xfs_mount_t *mp = ip->i_mount; + struct inode *inode = XFS_ITOV(ip); int mask = iattr->ia_valid; xfs_trans_t *tp; int code; @@ -446,6 +447,9 @@ xfs_setattr( ip->i_d.di_mode &= S_IFMT; ip->i_d.di_mode |= iattr->ia_mode & ~S_IFMT; + inode->i_mode &= S_IFMT; + inode->i_mode |= iattr->ia_mode & ~S_IFMT; + xfs_trans_log_inode (tp, ip, XFS_ILOG_CORE); timeflags |= XFS_ICHGTIME_CHG; } @@ -481,6 +485,7 @@ xfs_setattr( &ip->i_udquot, udqp); } ip->i_d.di_uid = uid; + inode->i_uid = uid; } if (igid != gid) { if (XFS_IS_GQUOTA_ON(mp)) { @@ -491,6 +496,7 @@ xfs_setattr( &ip->i_gdquot, gdqp); } ip->i_d.di_gid = gid; + inode->i_gid = gid; } xfs_trans_log_inode (tp, ip, XFS_ILOG_CORE); @@ -503,12 +509,14 @@ xfs_setattr( */ if (mask & (ATTR_ATIME|ATTR_MTIME)) { if (mask & ATTR_ATIME) { + inode->i_atime = iattr->ia_atime; ip->i_d.di_atime.t_sec = iattr->ia_atime.tv_sec; ip->i_d.di_atime.t_nsec = iattr->ia_atime.tv_nsec; ip->i_update_core = 1; timeflags &= ~XFS_ICHGTIME_ACC; } if (mask & ATTR_MTIME) { + inode->i_mtime = iattr->ia_mtime; ip->i_d.di_mtime.t_sec = iattr->ia_mtime.tv_sec; ip->i_d.di_mtime.t_nsec = iattr->ia_mtime.tv_nsec; timeflags &= ~XFS_ICHGTIME_MOD; @@ -524,6 +532,7 @@ xfs_setattr( */ if ((flags & XFS_ATTR_DMI) && (mask & ATTR_CTIME)) { + inode->i_ctime = iattr->ia_ctime; ip->i_d.di_ctime.t_sec = iattr->ia_ctime.tv_sec; ip->i_d.di_ctime.t_nsec = iattr->ia_ctime.tv_nsec; ip->i_update_core = 1; -- cgit v1.2.3
