Hi, all I would like to ask if the conflict between xfs inode recycle and vfs rcu-walk which can lead to null pointer references has been resolved? I browsed through emails about the following patches and their discussions: - https://lore.kernel.org/linux-xfs/20220217172518.3842951-2-bfoster@xxxxxxxxxx/ - https://lore.kernel.org/linux-xfs/20220121142454.1994916-1-bfoster@xxxxxxxxxx/ - https://lore.kernel.org/linux-xfs/164180589176.86426.501271559065590169.stgit@xxxxxxxxxxxxxxxxx/ And then came to the conclusion that this problem has not been solved, am I right? Did I miss some patch that could solve this problem? According to my understanding, the essence of this problem is that XFS reuses the inode evicted by VFS, but VFS rcu-walk assumes that this will not happen. Are there any recommended workarounds until an elegant and efficient solution can be proposed? After all, causing a crash is extremely unacceptable in a production environment. Thank you very much for your advice :) Jinliang Zheng
