4 Fuse I/O Modes
7 Fuse supports the following I/O modes:
9 - direct-io
10 - cached
11   + write-through
12   + writeback-cache
14 The direct-io mode can be selected with the FOPEN_DIRECT_IO flag in the
17 In direct-io mode the page cache is completely bypassed for reads and writes.
18 No read-ahead takes place. Shared mmap is disabled by default. To allow shared
21 In cached mode reads may be satisfied from the page cache, and data may be
22 read-ahead by the kernel to fill the cache.  The cache is always kept consistent
26 write-through mode is the default and is supported on all kernels.  The
27 writeback-cache mode may be selected by the FUSE_WRITEBACK_CACHE flag in the
30 In write-through mode each write is immediately sent to userspace as one or more
35 In writeback-cache mode (enabled by the FUSE_WRITEBACK_CACHE flag) writes go to
36 the cache only, which means that the write(2) syscall can often complete very
