// By default, fuse invalidates the kernel's page cache for an inode when a

// intent appears to be to allow users to "see" content that has changed
// remotely on a networked file system by re-opening the file.

// For file systems where this is not a concern because all modifications for
// a particular inode go through the kernel, set this field to true to
// disable this behavior.
