Subject: How does ftruncate() interact with DIO read?
Date: Fri, 03 Feb 2023 16:27:10 +0000 [thread overview]
Message-ID: <2116614.1675441630@warthog.procyon.org.uk> (raw)

Hi Christoph,
What does ftruncate() do if there's a conflicting DIO read happening on the
same file? Does it cancel the bio?
David
