Subject: Re: [PATCH 09/17] mm: export access_remote_vm() symbol
Date: Sun, 8 Jan 2023 09:36:06 -0800 [thread overview]
Message-ID: <Y7r/BjWEP2q64TGy@infradead.org> (raw)
In-Reply-To: <Y7RpuqbTAM11wVQG@lucifer>
Exporting access_remote_vm just seems like a horrible idea.
If a driver needs to access a different VM from a completion path
in some thread or workqueue (which I assume this does, if not please
explain the use case), it should use kthread_use_mm to associate the
mm struct and then just use all the normal uaccess helpers.
