XFS binary code size

[Stan Hoeppner]

I'm curious about the footprint of the XFS binary code, specifically for 
32 bit systems, but knowing the 64 bit case would be educational as well 
for comparison.  I don't use kernel modules or I'd already have a rough 
answer.  My last build was 2.6.38.6 but I'm sure the size hasn't changed 
much in more recent kernels.  My XFS build options were:

$ grep -i xfs .config
CONFIG_XFS_FS=y
# CONFIG_XFS_QUOTA is not set
# CONFIG_XFS_POSIX_ACL is not set
# CONFIG_XFS_RT is not set

My resulting kernel image is:
$ la /boot/vmlinuz-2.6.38.6
-rw-r--r--  1 root root 1.6M May 17 23:55 vmlinuz-2.6.38.6

How much of that 1.6MB is XFS?  Also, what is the size of the hot path 
code that we want to stay in L1 during heavy IO?
