Bug ID: 206238
Summary: FUSE can't enter to DIRECT_IO mode during file create.
Product: Base System
Version: 10.2-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern

When we want to use direct IO flag it's mostly working ok.
But in very specific situation still uses cache omitting DIRECT FLAG.
This situation appears only when we are creating file.
We suspect that this problem is connected with function:
fuse_vnode_open(vp, 0, td)
in /usr/src/sys/fs/fuse/fuse_fnops.c file.
The second parameter of this function is always set to 0 value and in some
cases removing DIRECT flag set by other functions.
