By default this is set to the + same value as the readahead:offset option and if not + set explicitly will use the current value of + readahead:offset. + + This module is stackable. + + + + OPTIONS + + + + + readahead:offset = BYTES + + The offset multiple that causes readahead to be + requested of the kernel buffer cache. + + + + + readahead:length = BYTES + + The number of bytes requested to be + read into the kernel buffer cache on each + readahead call. + + + + The following suffixes may be applied to BYTES: + + K - BYTES is a number of kilobytes + M - BYTES is a number of megabytes + G - BYTES is a number of gigabytes + + + + + + + + EXAMPLES + + + + readahead + + + + + + VERSION + This man page is correct for version 3.0.25 of the Samba suite. + + + + + AUTHOR + + The original Samba software and related utilities + were created by Andrew Tridgell.
