Subject: tracing/blktrace: move the tracing file to kernel/trace, fix
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1dfba05d0f1a9b4245bb242a7c17fe448811a520;p=openwrt%2Fstaging%2Fblogic.git

tracing/blktrace: move the tracing file to kernel/trace, fix

Impact: build fix

The BLK_DEV_IO_TRACE entry used to be in block/Kconfig - which
file itself was dependent on CONFIG_BLOCK. But now the entry is
in kernel/trace/Kconfig - which is present even on !CONFIG_BLOCK.

So add a 'depends on BLOCK' to BLK_DEV_IO_TRACE.
