-'kernel_cache'
-
- This option disables flushing the cache of the file contents on
- every open(). This should only be enabled on filesystems, where the
- file data is never changed externally (not through the mounted FUSE
- filesystem). Thus it is not suitable for network filesystems and
- other "intermediate" filesystems.
-
- NOTE: if this option is not specified (and neither 'direct_io') data
- is still cached after the open(), so a read() system call will not
- always initiate a read operation.
-
-'direct_io'
-
- This option disables the use of page cache (file content cache) in
- the kernel for this filesystem. This has several affects:
-
- - Each read() or write() system call will initiate one or more
- read or write operations, data will not be cached in the
- kernel.
-
- - The return value of the read() and write() system calls will
- correspond to the return values of the read and write
- operations. This is useful for example if the file size is not
- known in advance (before reading it).
-
'max_read=N'
With this option the maximum size of read operations can be set.
