This is a series of cleanups I'm planning to send to the next merge
window.
In the middle of bug hunting for a reported corruption problem, I felt
some more cleanup is necessary for maintenance mainly around the btree
code. This round I'd like to cut out the cleanup with this unless
required for other improvement.
As usual, these are not applicable to the standalone package and users
do not have to apply these piece by piece; they will be applied to the
module package after merged upstream.
Thanks,
Ryusuke Konishi

Even though many btree functions take a btree object as their first
argument, most of them are not used in their functions.
This sticky use of the btree argument is hurting code readability and
giving the possibility of inefficient code generation.
So, this removes unnecessary btree argments.

The btree path object is cleared just before it is freed.
This will remove the code doing the unnecessary clear operation.

This gets rid of NILFS_CPFILE_GFP, NILFS_SUFILE_GFP, NILFS_DAT_GFP,
and NILFS_IFILE_GFP. All of these constants refer to NILFS_MDT_GFP,
and can be removed.

This is a preparation for the successive cleanup ("nilfs2: allow btree
to directly call dat operations").
This adds functions bundling a few operations to change an entry of
virtual block address on the dat file.

The current btree code is written so that btree functions call dat
operations via wrapper functions in bmap.c when they allocate, free,
or modify virtual block addresses.
This abstraction requires additional function calls and causes
frequent call of nilfs_bmap_get_dat() function since it is used in the
every wrapper function.
This removes the wrapper functions and makes them available from
btree.c and direct.c, which will increase the opportunity of
compiler optimization.

From: Ryusuke Konishi @ 2009-08-16 6:51 UTC (permalink / raw)
To: users-JrjvKiOkagjYtjvyW6yDsg; +Cc: Ryusuke Konishi
The nilfs_bmap_lookup() is now a wrapper function of
nilfs_bmap_lookup_at_level().
This moves the nilfs_bmap_lookup() to a header file converting it to
an inline function and gives an opportunity for optimization.
