Subject: Question: Why is there no notification when a file is opened using filp_open()?
Date: Tue, 8 Sep 2020 16:01:48 +0800	[thread overview]
Message-ID: <25817189-49a7-c64f-26ee-78d4a27496b6@huawei.com> (raw)

The file opening action on the system may be from user-mode sys_open() 
or kernel-mode filp_open().
Currently, fsnotify_open() is invoked in do_sys_openat2().
But filp_open() is not notified. Why? Is this an omission?

Do we need to call fsnotify_open() in filp_open() or  do_filp_open() to 
ensure that both user-mode and kernel-mode file opening operations can 
be notified?

Thanks
Xiaoming Ni
