Are they not? The low-memory patchset has been released in 4.7.1, the
devel branch is always on top of master branch. I see both branches
pushed to the public git repos so I don't see what you mean.

Unfortunately, the low memory mode is not fully merged into devel branch.

Only the first part (extent and chunk tree) is merged.

The second part(fs tree) is not merged yet.

Patches like the following is not in either devel/master branch:
Lu Fengqi (13):
    btrfs-progs: move btrfs_extref_hash() to hash.h
    btrfs-progs: check: introduce function to find dir_item
    btrfs-progs: check: introduce function to check inode_ref
    btrfs-progs: check: introduce function to check inode_extref
    btrfs-progs: check: introduce function to find inode_ref
    btrfs-progs: check: introduce a function to check dir_item
    btrfs-progs: check: introduce function to check file extent
    btrfs-progs: check: introduce function to check inode item
    btrfs-progs: check: introduce function to check fs root
    btrfs-progs: check: introduce function to check root ref
    btrfs-progs: check: introduce low_memory mode fs_tree check
    btrfs-progs: check: fix the return value bug of cmd_check()
    btrfs-progs: check: fix false warning for check_extent_item()

So Wang found it confusing and unable to apply his patch to devel branch.

He could have replied himself, I think the conversation would feel
better when we can talk directly :)

Yes, I agree. I was on leave for a while this morning :)

Doh, I may be confused by the names, I mean that I've never seen a mail
from 'Lu Fengqi'.
