I've experienced a strange issue with zlib_inflate on x84_64 system.
There is no zlib_inflate-related symbols at /proc/kallsyms and modules like btrfs couldn't be loaded.

17.01 branch and the current master branch, both are affected.

Steps to reproduce:

  1. Use attached config file (zlib_inflate-test-config). It's almost default but I've set CONFIG_PACKAGE_kmod-fs-btrfs=y and some other options.
  2. Compile LEDE:
    make defconfig && make -j $(nproc)
  3. Run qemu:
    qemu-system-x86_64 -curses -kernel bin/targets/x86/64/lede-x86-64-ramfs.bzImage
  4. Try to load btrfs module:
    root@LEDE:/# modprobe btrfs
    [ 23.345891] btrfs: Unknown symbol zlib_inflateInit2 (err 0)
    [ 23.347096] btrfs: Unknown symbol zlib_inflate (err 0)
    [ 23.347673] btrfs: Unknown symbol zlib_inflate_workspacesize (err 0)
    [ 23.348293] btrfs: Unknown symbol zlib_inflateEnd (err 0)

It's not btrfs related but any module with zlib_inflate in it's dependency list.

Looks like it's broken since [[https://github.com/lede-project/source/commit/7c874d18f51cb952babd8241fae5a8286dc68878|7c874d1]]. The last working commit is [[https://github.com/lede-project/source/commit/93fb6ce05b1e161a8a5485e006e5fe05fc060fd3|93fb6ce]]
