on ia-64, I see the following (2.4.18, with gcc3.1):
- ext2_follow_link(): 16 bytes/frame
- vfs_follow_link(): 56 bytes/frame
- link_path_walk(): 128 bytes/frame
--------------------- ---------------
total: 200 bytes/frame
Just about in line with what you'd expect given that registers are
64 bits.
On sparc64 the situation is much worse (due to register windows)
which means any non-leaf function (function which invokes no nother
functions) equals 192 bytes of stack space per frame minimum.
