85 | This option disables flushing the cache of the file contents on | ||
86 | every open(). This should only be enabled on filesystems, where the | ||
87 | file data is never changed externally (not through the mounted FUSE | ||
88 | filesystem). Thus it is not suitable for network filesystems and | ||
89 | other "intermediate" filesystems. | ||
90 | |||
91 | NOTE: if this option is not specified (and neither 'direct_io') data | ||
92 | is still cached after the open(), so a read() system call will not | ||
93 | always initiate a read operation. | ||

95 | 'direct_io' | ||
96 | |||
97 | This option disables the use of page cache (file content cache) in | ||
98 | the kernel for this filesystem. This has several affects: | ||
99 | |||
100 | - Each read() or write() system call will initiate one or more | ||
101 | read or write operations, data will not be cached in the | ||
102 | kernel. | ||
103 | |||
104 | - The return value of the read() and write() system calls will | ||
105 | correspond to the return values of the read and write | ||
106 | operations. This is useful for example if the file size is not | ||
107 | known in advance (before reading it). | ||
