Hi @prasad-acit , nice to talk to you.
For delete using FGL, it may be safer to add child locks before fsn.removeLeasesAndINodes().
The reason here is that after finishing running unprotectedDelete(), there are still updated content, such as block-related updates, and snapshotManager deletes Snapshottable.
Before this, this was done while holding the FSNamesystemLock.
Based on the premise of safety, I make my proposal.
If my suggestion is wrong, please ignore it.
