+Subject: [PATCH v5 0/5] Add xxhash and zstd modules
+
+Hi all,
+
+This patch set adds xxhash, zstd compression, and zstd decompression
+modules. It also adds zstd support to BtrFS and SquashFS.
+
+Each patch has relevant summaries, benchmarks, and tests.
+
+Best,
+Nick Terrell
+
+Changelog:
+
+v1 -> v2:
+- Make pointer in lib/xxhash.c:394 non-const (1/5)
+- Use div_u64() for division of u64s (2/5)
+- Reduce stack usage of ZSTD_compressSequences(), ZSTD_buildSeqTable(),
+  ZSTD_decompressSequencesLong(), FSE_buildDTable(), FSE_decompress_wksp(),
+  HUF_writeCTable(), HUF_readStats(), HUF_readCTable(),
+  HUF_compressWeights(), HUF_readDTableX2(), and HUF_readDTableX4() (2/5)
+- No zstd function uses more than 400 B of stack space (2/5)

+- Port upstream BtrFS commits e1ddce71d6, 389a6cfc2a, and 6acafd1eff (3/5)
+- Change default compression level for BtrFS to 3 (3/5)
+
+v3 -> v4:
+- Fix compiler warnings (2/5)
+- Add missing includes (3/5)
+- Fix minor linter warnings (3/5, 4/5)
