| A sorted list of bad stack users (more than 256 bytes) in my default build | follows. Anybody can create their own with something like | | objdump -d linux/vmlinux | | grep 'sub.*$0x...,.*esp' | | awk '{ print $9,$1 }' | | sort > bigstack | | and a script to look up the addresses. | | That ide_unregister() thing uses up >2kB in just one call! And there are | several in the 1.5kB range too, with a long list of ~500 byte offenders. | | Yeah, and this assumes we don't have alloca() users or other dynamic | stack allocators (non-constant-size automatic arrays). I hope we don't | have that kind of crap anywhere..
Keith Owens did such a script over 1 year ago. It's available from http://kernelnewbies.org/scripts/check-stack.sh It also identifies (flags) dynamic stack allocation. (course, I can't read Keith's as well as I can Linus's)
