Subject: [PATCH v5 2/9] lib: zstd: Add decompress_sources.h for decompress_unzstd
Date: Mon,  2 Nov 2020 22:05:28 -0800	[thread overview]
Message-ID: <20201103060535.8460-3-nickrterrell@gmail.com> (raw)
In-Reply-To: <20201103060535.8460-1-nickrterrell@gmail.com>

From: Nick Terrell <terrelln@fb.com>

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. Instead we just need to update decompress_sources.h.
