The patch titled
Subject: mm/swap: make swap_address_space an inline function
has been removed from the -mm tree. Its filename was
mm-swap-make-swap_address_space-an-inline-function.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mel Gorman <mgorman@xxxxxxxxxxxxxxxxxxx>
Subject: mm/swap: make swap_address_space an inline function
make W=1 generates the following warning in page_mapping() for allnoconfig
mm/util.c:700:15: warning: variable `entry' set but not used [-Wunused-but-set-variable]
swp_entry_t entry;
^~~~~
swap_address is a #define on !CONFIG_SWAP configurations. Make the helper
an inline function to suppress the warning, add type checking and to apply
any side-effects in the parameter list.
