Subject: [PATCH v1 1/1] erofs-utils: fix endiannes issue
Date: Tue, 29 Apr 2025 09:30:52 +0200	[thread overview]
Message-ID: <20250429073052.53681-1-egorenar@linux.ibm.com> (raw)

From: Super User <root@a8345034.lnxne.boe>

Macros __BYTE_ORDER, __LITTLE_ENDIAN and __BIG_ENDIAN are defined in
user space header 'endian.h'. Not including this header results in
the condition #if __BYTE_ORDER == __LITTLE_ENDIAN being always true, even on
BE architectures (e.g. s390x). Due to this bug the compressor library was
built for LE byte-order on BE arch s390x.

Fixes: bc99c763e3fe ("erofs-utils: switch to effective unaligned access")
