Okay then, I suppose there is no nice way around that, or at least none
that I can find. I'll just make that initial buffer 12kb big on my kernel
for that device and be done with it.
Anyway, thanks for the information and help, it is much appreciated.

It only needs to survive until init_atags_procfs is called, because it is
copied to another buffer for procfs entry. Can I be sure it survives until
that? My guess is that it is likely to survive, but not certain.
I suppose it is possible to somehow protect that bit of ram until it is

Hello,
I want to ask something about atags_proc.c implementation. Currently,
it uses a buffer to temporarily store atags. The buffer size is set to
1.5kb for some reason, but as far as I know, atag list's size is not
limited in any way. I've got a device (HTC One) which uses about 12kb
of tags,

It only needs to survive until init_atags_procfs is called, because it is
copied to another buffer for procfs entry. Can I be sure it survives until
that? My guess is that it is likely to survive, but not certain.
