Subject: question: should io_is_direct really return true for DAX inodes?
Date: Thu, 29 Oct 2015 10:32:45 -0400 [thread overview]
Message-ID: <x4937wtd9te.fsf@segfault.boston.devel.redhat.com> (raw)
Hi,
I'm concerned that applications that used to run out of page cache will
experience a performance degradation when being forced into doing I/O
directly to the backing store. What do others think?
Cheers,
Jeff
