    [PATCH] checkstack: print module names · 8ad2914d
    Randy Dunlap authored
    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.
