From: Zijun Hu Date: Wed, 7 May 2025 11:50:26 +0000 (+0800) Subject: configfs: Do not override creating attribute file failure in populate_attrs() X-Git-Tag: v5.15.186~221 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8cb51a55b26eadc671748adbac12ebb2375ec9c1;p=thirdparty%2Fkernel%2Fstable.git configfs: Do not override creating attribute file failure in populate_attrs() commit f830edbae247b89228c3e09294151b21e0dc849c upstream. populate_attrs() may override failure for creating attribute files by success for creating subsequent bin attribute files, and have wrong return value. Fix by creating bin attribute files under successfully creating attribute files.
