Reads/Writes through the cache layer.

This function performs I/O, either using the Ganesha in-memory or disk cache or through the FSAL directly. The caller MUST NOT hold either the content or attribute locks when calling this function.

Parameters:

[in]	entry	File to be read or written
[in]	io_direction	Whether this is a read or a write
[in]	offset	Absolute file position for I/O
[in]	io_size	Amount of data to be read or written
[out]	bytes_moved	The length of data successfuly read or written
[in,out]	buffer	Where in memory to read or write data
[out]	eof	Whether a READ encountered the end of file. May be NULL for writes.
[in]	context	FSAL credentials
[in]	stable	The stability of the write to perform
[out]	status	Status of operation

Returns:

CACHE_INODE_SUCCESS or various errors
