lib: find_last_bit.o needed by a module only, move it from lib to obj

2009-04-24T20:28:31Z

Currently, although find_last_bit is EXPORTed, it is statically linked with the kernel and is referenced only under CONFIG_SMP. When CONFIG_SMP is undefined and find_last_bit is referenced only by modules, linking fails with: ERROR: "find_last_bit" [fs/nfs/nfs.ko] undefined!

dynamic debug: combine dprintk and dynamic printk

2009-03-24T23:38:26Z

This patch combines Greg Bank's dprintk() work with the existing dynamic printk patchset, we are now calling it 'dynamic debug'. The new feature of this patchset is a richer /debugfs control file interface, (an example output from my system is at the bottom), which allows fined grained control over the the debug output. The output can be controlled by function, file, module, format string, and line number. for example, enabled all debug messages in module 'nf_conntrack': echo -n 'module nf_conntrack +p' > /mnt/debugfs/dynamic_debug/control to disable them: echo -n 'module nf_conntrack -p' > /mnt/debugfs/dynamic_debug/control A further explanation can be found in the documentation patch.

netlink: Move netlink attribute parsing support to lib

2009-03-04T06:53:30Z

Netlink attribute parsing may be used even if CONFIG_NET is not set. Move it from net/netlink to lib and control its inclusion based on the new config symbol CONFIG_NLATTR, which is selected by CONFIG_NET. Signed-off-by: Geert Uytterhoeven Acked-by: David S. Miller Signed-off-by: Herbert Xu
