Ignoring docs and fs/inode.c, we have 80 files changed, 190 insertions(+), 494 deletions(-) IOW, just over 300 lines of boiler plate code removed. The additions are - Ten more lines of actual code in fs/inode.c (and that's not actually added complexity, it looks simpler if anything - most of it is the new "i_callback()" helper function) - 19 lines of doc updates. So it absolutely looks fine to me. I only skimmed through the actual filesystem (and one networking) patches, but they looked like trivial conversions to a better interface. Linus
