BTRFS uses bio->bi_vcnt to figure out page numbers, this way becomes not
correct once we start to enable multipage bvec.
So use bio_nr_pages() to do that instead.

It is enough to check and compute bio->bi_seg_front_size just
after the 1st segment is found, but current code checks that

This patch follows the way in __blk_recalc_rq_segments()

and code becomes
When merging one bvec into segment, if the bvec is too big

This patchset changes the policy into trying to maximize size of

is merged into current segment, and t

v1 -> v2: use child_info to pass dentry namelen
v2 -> v3: check child != NULL to include the F2FS_FT_ORPHAN file type
v3 -> v4: fix the i_namelen problem of dump.f2fs

are disabled:

The new debugfs registration fails to build when CONFIG_DEBUGFS is
disabled, because the drm_crtc structure is lacking a member in that
configuration:
drivers/gpu/drm/tegra/dc.c: In function 'tegra_dc_late_register':
drivers/gpu/drm/tegra/dc.c:1204:28: error: 'struct drm_crtc' has no member
named
