We should probably take a snapshot at least (I don't think it'll fix this though). We want at least: * https://github.com/kilobyte/compsize/commit/9f02a12c377e5ac12544b0d07d73eb7c352a4787 * https://github.com/kilobyte/compsize/commit/a7bf82296193f785757f0cb30627dce30462f085 * https://github.com/kilobyte/compsize/commit/4288964fd32dc5a00c7162e5ab9920039e5a5e14 But I haven't looked at what commit(s) in btrfs-progs broke this (per upstream bug).
These two commits, at least, are mentioned by NixOS folks: - https://github.com/kdave/btrfs-progs/commit/2830e841359e456ab14e48aabaedab8a2276e484 - https://github.com/kdave/btrfs-progs/commit/2f297355c9b1c451c3ad2bfd07a368ef69b9b8d7 They remove a bunch of junk which approximates kernel internals using libc equivalents.
In radix-tree.h in compsize, there's the following bit: #if BTRFS_FLAT_INCLUDES #include "kerncompat.h" #else #include <btrfs/kerncompat.h> #endif /* BTRFS_FLAT_INCLUDES */ Their bundled kerncompat.h includes definitions for stuff like gfp_t which were removed from btrfs-progs kerncompat.h.
This is actually a problematic flag because defining it for compsize has implications when it comes to libbtrfs. From libbtrfs/ctree.h as an example: #if BTRFS_FLAT_INCLUDES #include "libbtrfs/kerncompat.h" #include "kernel-lib/rbtree_types.h" #include "libbtrfs/ioctl.h" #else #include <btrfs/kerncompat.h> #include <btrfs/rbtree_types.h> #include <btrfs/ioctl.h> #endif /* BTRFS_FLAT_INCLUDES */ https://github.com/kdave/btrfs-progs/blob/c75b2f2c77c9fdace08a57fe4515b45a4616fa21/libbtrfs/ctree.h#L24
Taking a closer look at what compsize has, their radix-tree.c and radix-tree.h appear to be 7 year old copies of btrfs-progs sources...
