From: John Garry Date: Tue, 7 Aug 2018 13:15:05 +0000 (+0800) Subject: ACPI / scan: Add static attribute to indirect_io_hosts[] X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a6f0729508df6a067c4a074ec187ecd9d2457a6b;p=linux.git ACPI / scan: Add static attribute to indirect_io_hosts[] Array indirect_io_hosts[] is declared in acpi_is_indirect_io_slave() as a const array, which means that the array will be re-built for each call. Optimise by adding the static attribute, which means that the array is added to const-data pool and not re-built per function call.
