Hi,
I wanted to understand the behavior taken when a module calls debugfs_remove_recursive() on a directory, while files under that directory may still be in use by the userspace (for instance an ongoing read / write operation).
Does the function wait
(1) until all the currently executing file operation methods (read/write/map etc) have returned? OR (2) until the user has given up all references (descriptors) to the files under the directory (i.e. until release() method has been called)?
Thanks,
Rajat
