My email (gmail account) has been so weird recently. I don't know why
I'm not getting Fabio's emails... Presumably they will show up in a few
days.
The other command to use is:
$ ./smatch/smatch_data/db/smdb.py preempt ips_leave
rtw_set_802_11_disassociate() <- disables preempt
-> _rtw_pwr_wakeup()
-> LeaveAllPowerSaveMode()
-> ips_leave()
I save that to a file, open it with with vim and run a vim function
`hall` (for highlight all) from my .vimrc file.
" Use :hall to highlight all the words in a file (for debugging sleeping bugs)
function HLall()
let a=[]
%s/\w\+/\=add(a, submatch(0))/gn
let @/ = join(a, "\\|")
endfunction
cnoreabbrev hall call HLall() <CR>:set hls<CR>
That highlights all the functions is the call tree, then I use cscope to
jump to rtw_set_802_11_disassociate and follow the highlighted functions
to ips_leave().
