[PATCH] checkstack: print module names
Finding "init_module" high stack usage problems is challenging when there
are over 1600 "init_module" functions in the kernel tree, so make
checkstack.pl print out the filename where the stack usage occurs. This is
useful for code built as loadable modules.
For built-in code, it just prints the kernel image file name, like
"vmlinux". Examples:
(before patch:)
0x0000000d callback: 1928
0xffffffff81678c09 huft_build: 1560
0x0018 init_module: 1512
(after patch:)
0x0000000d callback [divacapi]: 1928
0xffffffff81678c09 huft_build [vmlinux]: 1560
0x0018 init_module [hdaps]: 1512
Also change one if-series to use elsif to cut down on unneeded tests.
