The 0079-netdev-destructor.cocci spatch in backports is very slow for me. For bigger files I get a warning that it takes over to 15 seconds to apply it to just one file, for the complete backports tree it takes over an hour to apply. This is the patch: https://git.kernel.org/pub/scm/linux/kernel/git/backports/backports.git/tree/patches/0079-netdev-destructor.cocci When I remove the <-- --> in the first rule, it is applied in some seconds on the complete tree, so an speed improvement of about 100 times, but it is not working correctly any more. ;-) Is this normal or how can I improve the spatch to be faster? I am using coccinelle 1.0.7 build with default configure arguments against the libraries from Debian stable. If this is normal I should probably try to reduce the number of files it tries to apply this against in gentree.py before spatch gets started. Hauke
