[lustre-devel] [PATCH 3/7] lustre/libfs: move debugfs registration from libcfs_setup back to libcfs_init

[NeilBrown]

large memory allocations should be avoided at module-init,
but registering services is appropriate.
So move the registration of debugfs files
back into libcfs_init().
Without this, /sys/kernel/debug/lnet etc are not visible
immediately that libcfs is loaded.
No debugfs file access needs anything allocated by libcfs_setup().

Fixes: 64bf0b1a079d ("staging: lustre: refactor libcfs initialization.")
