The patch titled
ext4: le*_add_cpu conversion
has been removed from the -mm tree. Its filename was
ext4-le_add_cpu-conversion.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: ext4: le*_add_cpu conversion
From: Marcin Slusarz <[email protected]>
replace all:
little_endian_variable = cpu_to_leX(leX_to_cpu(little_endian_variable) +
expression_in_cpu_byteorder);
with:
leX_add_cpu(&little_endian_variable, expression_in_cpu_byteorder);
generated with semantic patch
