From: Shijie Luo Date: Fri, 12 Mar 2021 06:50:51 +0000 (-0500) Subject: ext4: fix potential error in ext4_do_update_inode X-Git-Tag: v4.4.263~2 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fdcae89f04f1e4cb66143e4c2a291359dfda50f6;p=thirdparty%2Fkernel%2Fstable.git ext4: fix potential error in ext4_do_update_inode commit 7d8bd3c76da1d94b85e6c9b7007e20e980bfcfe6 upstream. If set_large_file = 1 and errors occur in ext4_handle_dirty_metadata(), the error code will be overridden, go to out_brelse to avoid this situation.
