Subject: [PATCH] bcachefs: Fix error path of bch2_link_trans()
Date: Tue, 30 Apr 2024 11:28:39 +0800
Message-Id: <20240430032839.948404-1-youling.tang@linux.dev>

From: Youling Tang <tangyouling@kylinos.cn>

In bch2_link_trans(), if bch2_inode_nlink_inc() fails, it needs to
call bch2_trans_iter_exit() in the error path.
