[XFS] Avoid directly referencing the VFS inode.

2008-08-13T05:45:15+00:00

In several places we directly convert from the XFS inode
to the linux (VFS) inode by a simple deference of ip->i_vnode.
We should not do this - a helper function should be used to
extract the VFS inode from the XFS inode.

Introduce the function VFS_I() to extract the VFS inode
from the XFS inode. The name was chosen to match XFS_I() which
is used to extract the XFS inode from the VFS inode.

[XFS] remove manual lookup from xfs_rename and simplify locking

2008-04-29T05:54:12+00:00

->rename already gets the target inode passed if it exits. Pass it down to
xfs_rename so that we can avoid looking it up again. Also simplify locking
as the first lock section in xfs_rename can go away now: the isdir is an
invariant over the lifetime of the inode, and new_parent and the nlink
check are namespace topology protected by i_mutex in the VFS. The projid
check needs to move into the second lock section anyway to not be racy.

Also kill the now unused xfs_dir_lookup_int and remove the now-unused
first_locked argumet to xfs_lock_inodes.

[XFS] shrink mrlock_t

2008-04-29T05:54:02+00:00

The writer field is not needed for non_DEBU builds so remove it. While
we're at i also clean up the interface for is locked asserts to go through
and xfs_iget.c helper with an interface like the xfs_ilock routines to
isolated the XFS codebase from mrlock internals. That way we can kill
mrlock_t entirely once rw_semaphores grow an islocked facility. Also
remove unused flags to the ilock family of functions.

[XFS] kill xfs_get_dir_entry

2008-04-18T01:39:14+00:00

Instead of of xfs_get_dir_entry use a macro to get the xfs_inode from the
dentry in the callers and grab the reference manually.

Only grab the reference once as it's fine to keep it over the dmapi calls.
(And even that reference is actually superflous in Linux but I'll leave
that for another patch)

Remove macro-to-small-function indirection from xfs_sb.h, and remove some
which are completely unused.

[XFS] keep i_nlink updated and use proper accessors

2008-02-07T07:23:38+00:00

To get the read-only bind mounts in -mm to work correctly with XFS we need
to call the drop_nlink and inc_nlink helpers to monitor the link count.
Add calls to these to xfs_bumplink and xfs_droplink and stop copying over
di_nlink to i_nlink in xfs_validate_fields and vn_revalidate.

2008-02-07T05:47:15+00:00

Un-obfuscate XFS_SB_LOCK, remove XFS_SB_LOCK->mutex_lock->spin_lock
macros, call spin_lock directly, remove extraneous cookie holdover from
old xfs code, and change lock type to spinlock_t.

[XFS] clean up vnode/inode tracing

2008-02-07T05:42:19+00:00

Simplify vnode tracing calls by embedding function name & return addr in
the calling macro.

Also do a lot of vnode->inode renaming for consistency, while we're at it.

[XFS] move v_trace from bhv_vnode to xfs_inode

2007-10-16T01:39:25+00:00

struct bhv_vnode is on it's way out, so move the trace buffer to the XFS
inode. Note that this makes the tracing macros rather misnamed, but this
kind of fallout will be fixed up incrementally later on.
