nilfs2: record used amount of each checkpoint in checkpoint list

2011-03-08T05:58:31+00:00

This records the number of used blocks per checkpoint in each
checkpoint entry of cpfile.  Even though userland tools can get the
block count via nilfs_get_cpinfo ioctl, it was not updated by the
nilfs2 kernel code.  This fixes the issue and makes it available for
userland tools to calculate used amount per checkpoint.

nilfs2: remove redundant pointer checks in bmap lookup functions

2010-07-23T01:02:14+00:00

nilfs_bmap_lookup and its variants are supposed to take a valid
pointer argument to return a block address, thus pointer checks in
nilfs_btree_lookup and nilfs_direct_lookup are needless.

nilfs2: unify bmap set_target_v operations

2010-07-23T01:02:14+00:00

This unifies two similar functions nilfs_btree_set_target_v and
nilfs_direct_set_target_v into one, nilfs_bmap_set_target_v.

nilfs2: get rid of nilfs_direct uses

2010-07-23T01:02:13+00:00

This replaces all uses of nilfs_direct struct in implementation of
direct mapping with nilfs_bmap struct.

nilfs2: remove constant qualifier from argument of bmap propagate

2010-07-23T01:02:13+00:00

The first argument of bops->bop_propagate operation takes a constant
qualifier, and causes compilation error when removed cast to pointer
of nilfs_btree structure type.  This fixes the issue to prepare for
succesive removal of nilfs_btree struct.

nilfs2: get rid of private conversion macros on bmap key and pointer

2010-07-23T01:02:13+00:00

Will remove nilfs_bmap_key_to_dkey(), nilfs_bmap_dkey_to_key(),
nilfs_bmap_ptr_to_dptr(), and nilfs_bmap_dptr_to_ptr() for simplicity.

nilfs2: allow btree code to directly call dat operations

2009-09-14T09:27:16+00:00

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.

nilfs2: support contiguous lookup of blocks

2009-06-10T14:41:12+00:00

Although get_block() callback function can return extent of contiguous
blocks with bh->b_size, nilfs_get_block() function did not support
this feature.

This adds contiguous lookup feature to the block mapping codes of
nilfs, and allows the nilfs_get_blocks() function to return the extent
information by applying the feature.
