Hello,

trying to mount a zstd compressed ubifs fails on an iMX6ULL with

| ERROR: UBIFS error (ubi0:0): 9fe6691d: cannot decompress 2612 bytes, compressor zstd, error -22
| ERROR: UBIFS error (ubi0:0): 9fe6692d: cannot decompress 2612 bytes, compressor zstd, error -22
| ERROR: UBIFS error (ubi0:0): 9fe66a65: bad data node (block 0, inode 815)
| ERROR:  magic          0x6101831

(2022.09 and master).


After reverting

| commit b4a9782d4f56333e897dccc35c2c27e2605f6b93
| Author: Ahmad Fatoum <a.fatoum@pengutronix.de>
| Date:   Wed Jul 13 12:09:18 2022 +0200
| 
|     lib: zstd: sync with Linux

it works again (both in Linux 5.15 and barebox).


ubifs was created by recent OpenEmbedded kirkstone with

| MKUBIFS_ARGS = "-F -m 2048 -e 126976 -c 2048 --compr=zstd"


Warnings are triggered (after fixing assert()) at

| WARNING: at lib/zstd/decompress/../common/bitstream.h:390/BIT_reloadDStreamFast()!


Is anybody else experiencing these problems?



Enrico
