Subject: Question about dirty data for unlinked files
Date: Thu, 23 Mar 2017 13:07:23 -0700 [thread overview]
Message-ID: <CAGDaZ_qFMGuNMGzvOyStmtC9ZcCH3knHrhaOiP8HvmaphcWvVw@mail.gmail.com> (raw)
If you delete a file (and don't have it open), and there's a bunch of
dirty data for that file still in page cache, does all that dirty data
disappear or does it still get written back?
I'm curious for performance reasons because I have an experimental
process I'm developing, and it has a habit of leaving large amounts of
dirty data in a huge output file. I'd like to be able to unlink the
file and skip the writeback process once the file's been unlinked.
