[PATCH 0/9] Update to zstd-1.4.6

From: Nick Terrell This patchset upgrades the zstd library to the latest upstream release. The current zstd version in the kernel is a modified version of upstream zstd-1.3.1. At the time it was integrated, zstd wasn't ready to be used in the kernel as-is. But, it is now possible to use ups

[PATCH v7 1/3] lib: zstd: Add kernel-specific API

From: Nick Terrell This patch: - Moves `include/linux/zstd.h` -> `include/linux/zstd_lib.h` - Adds a new API in `include/linux/zstd.h` that is functionally equivalent to the in-use subset of the current API. Functions are renamed to avoid symbol collisions with zstd, to make it clear it

[PATCH v7 2/3] lib: zstd: Add decompress_sources.h for decompress_unzstd

From: Nick Terrell Adds decompress_sources.h which includes every .c file necessary for zstd decompression. This is used in decompress_unzstd.c so the internal structure of the library isn't exposed. This allows us to upgrade the zstd library version without modifying any callers. Inste
