Message-Id: <1294682207-10494-1-git-send-email-tytso@mit.edu> Date: Mon, 10 Jan 2011 12:56:47 -0500 From: Theodore Ts'o <tytso@....edu> To: Ext4 Developers List <linux-ext4@...r.kernel.org> Cc: hughd@...gle.com, Theodore Ts'o <tytso@....edu>, stable@...nel.org Subject: [PATCH] ext4: fix memory leak in ext4_free_branches Commit 40389687 moved a call to ext4_forget() out of ext4_free_branches and let ext4_free_blocks() handle calling bforget(). But that change unfortunately did not replace the call to ext4_forget() with brelse(), which was needed to drop the in-use count of the indirect block's buffer head, which lead to a memory leak when deleting files that used indirect blocks. Fix this. Thanks to Hugh Dickins for pointing this out.
