From: Zhen Ni Date: Fri, 14 Nov 2025 07:53:13 +0000 (+0800) Subject: btrfs: fix incomplete parameter rename in btrfs_decompress() X-Git-Tag: v6.19-rc1~167^2~41 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=280dd7c106fd4c47756d19f6ae89862bb7bf7225;p=thirdparty%2Fkernel%2Flinux.git btrfs: fix incomplete parameter rename in btrfs_decompress() Commit 2c25716dcc25 ("btrfs: zlib: fix and simplify the inline extent decompression") renamed the 'start_byte' parameter to 'dest_pgoff' in the btrfs_decompress(). The remaining 'start_byte' references are inconsistent with the actual implementation and may cause confusion for developers. Ensure consistency between function declaration and implementation.
