The patch titled
readahead: min/max sizes: remove get_readahead_bounds()
has been removed from the -mm tree. Its filename was
readahead-min-max-sizes-remove-get_readahead_bounds.patch
This patch was dropped because it was folded into readahead-min-max-sizes.patch
------------------------------------------------------
Subject: readahead: min/max sizes: remove get_readahead_bounds()
From: Fengguang Wu <wfg@xxxxxxxxxxxxxxxx>
Remove get_readahead_bounds():
- ra_max: we already have get_max_readahead() for it
- ra_min: is only used by context based readahead, and will be moved there
and set to a more reasonable value
