Subject: [PATCH 0/3] fix potential infinite loop in debugfs_remove_recursive
Date: Fri, 15 Nov 2019 11:27:49 +0800 [thread overview]
Message-ID: <1573788472-87426-1-git-send-email-yukuai3@huawei.com> (raw)
The first patch add a new enum type for 'dentry_d_lock_class'.The second
patch use the new enum type in 'simple_empty' to avoid confusion for
lockdep. The last patch fix potential infinite loop in
debugfs_remove_recursive by using 'simple_empty' instead of 'list_empty'.
yu kuai (3):
dcache: add a new enum type for 'dentry_d_lock_class'
fs/libfs.c: use 'spin_lock_nested' when taking 'd_lock' for dentry in
simple_empty
debugfs: fix potential infinite loop in debugfs_remove_recursive
