[PATCH STABLE 5.10] btrfs: harden identification of a stale device

by Anand Jain

commit 770c79fb65506fc7c16459855c3839429f46cb32 upstream Identifying and removing the stale device from the fs_uuids list is done by btrfs_free_stale_devices(). btrfs_free_stale_devices() in turn depends on device_path_matched() to check if the device appears in more than one btrfs_device structure. The matching of the device happens by its path, the device path. However, when device mapper is in use, the dm device paths are nothing but a link to the actual block device, which leads to the device_path_matched() failing to match. Fix this by matching the dev_t as provided by lookup_bdev() instead of plain string compare of the device paths.

[PATCH v2] mm/damon/dbgfs: fix memory leak when using

by SeongJae Park

From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> debugfs_lookup() Date: Fri, 2 Sep 2022 14:56:31 +0200 [thread overview] Message-ID: <20220902125631.128329-1-gregkh(a)linuxfoundation.org> (raw) When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. Fix this up by properly calling dput().
