Just to make sure - does that statement cover the following commit?

commit 0c85a7e87465f2d4cbc768e245f4f45b2f299b05
Author: Aditya Pakki <pakki001@umn.edu>
Date:   Tue Apr 6 19:09:12 2021 -0500

    net/rds: Avoid potential use after free in rds_send_remove_from_sock

And is "Ph.D. student in Computer Science" an accurate description of
the gentleman in question?

We all made utterly bonehead mistakes (if you want a fresh example
of mine, take a look at 161aff1d93ab "LOOKUP_MOUNTPOINT: fold
path_mountpointat() into path_lookupat()"; see 035d80695fae for the
merge of the fix and explanation of what was wrong in the original
commit).

However, there's a general expectation that once you become aware of
dumb mistake in something you have published (and merge into mainline
certainly qualifies as publication) you shall retract it as soon
as possible.  If a student is not aware of such expectation, their
advisor really ought to inform them of it.
