| |
Hi Marcel, I'm compiling current -git kernel and noticed this warning:
net/bluetooth/hci_sysfs.c: In function 'inquiry_cache_read': net/bluetooth/hci_sysfs.c:441: warning: the frame size of 4208 bytes is larger than 2048 bytes
which is caused by:
commit ca325f698996c1a0770a67f41e7dc97a007d8bc2 Author: Marcel Holtmann <marcel@holtmann.org> Date: Mon Feb 8 16:22:31 2010 +0100
Bluetooth: Convert inquiry cache to use debugfs instead of sysfs
The output of the inquiry cache is only useful for debugging purposes and so move it into debugfs.
This buffer on the stack:
char buf[4096];
is likelly to cause troubles, since the kernel space stack is limited to 8K or even 4K (4KSTACKS).
Luca
