5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jan Kara <jack@xxxxxxx> [ Upstream commit cb3b3bf22cf33707d684e74207908ba0ef3b6467 ] The name of jbd_debug() is confusing as all functions inside jbd2 have jbd2_ prefix. Rename jbd_debug() to jbd2_debug(). No functional changes.
