Last time I have proposed an API change for removing "pci_pool" , it was a patchset of 20 commits (something like this), it tooks 6 months to be merged :) (with a fine grain granularity on each commit) This is better to be the more atomic as possible. If we split the "one massive tasklet_init replacement" commit into many commit, I am sure that we find old tasklet API for months in the kernel... it is not something we want , imho. + treewide commits are common in the kernel tree, for important API changes :) @Kees: agreed ? I think that the timer_list approach is good. You can help by providing feedbacks and by testing if you want. Regards, Romain > > Thanks, > - Allen
