Subject: [PATCH v2 1/8] erofs: move several xattr helpers into xattr.c
Date: Thu, 30 Mar 2023 16:29:03 +0800 [thread overview]
Message-ID: <20230330082910.125374-2-jefflexu@linux.alibaba.com> (raw)
In-Reply-To: <20230330082910.125374-1-jefflexu@linux.alibaba.com>
Move xattrblock_addr() and xattrblock_offset() helpers into xattr.c,
as they are not used outside of xattr.c.
inlinexattr_header_size() has only one caller, and thus make it inlined
into the caller directly.
