Name	Describe
lookup_fast
may_delete	Check whether we can remove a link victim from directory dir, check* whether the type of victim is right.* 1. We can't do it if dir is read-only (done in permission())* 2. We should have write and exec permissions on dir* 3
atomic_open	Attempt to atomically look up, create and open a file from a negative* dentry
do_unlinkat	Make sure that the actual truncation of the file will occur outside its* directory's i_mutex. Truncate can take a long time if there is a lot of* writeout happening, and we don't want to prevent access to the directory* while waiting on the I/O.
