| |
With O_DIRECT (buffer cache bypass open() flag) now in the mainstream kernel, I wonder if people would be opposed to making a "direct" mount option, which would open all files on the filesystem with the O_DIRECT flag, just as there exists a "sync" mount option to perform filesystem transactions synchronously.
This would allow you to mount -o direct,sync /dev/hdb1 /mnt/video And would be useful for things like streaming video applications, allowing the advantages of O_DIRECT without rewriting every application you want to use.
Cheers, -- Bob
