# Pre13 L-E

The BSD-only miscellaneous `erofs_defs.h` has been removed. Its three owners
now keep their constants in the files responsible for those values:

- `super.c` owns the named private CRC32C seed.
- `dir.c` uses `sizeof(struct erofs_dirent)` directly.
- `decompressor_lz4.c` owns its private LZ4 format constants.

The former header had exactly these three production source consumers. All
constant values and use-site expressions remain equivalent. Two already
retired userspace decompression test files still referenced the removed header;
they were deleted because they also depended on obsolete userspace ABIs and did
not compile independently. No current source or test entry retains the old
include. The LZ4 macro names remain private to `decompressor_lz4.c`; the former
shared CRC and dirent macro names have no current consumers. The current
architecture file was updated; historical reports were not changed.

No KLD build, QEMU, smoke, or feature test was run for this batch.
