Eric Dumazet 8af27e1dc4 fixdep: use hash table instead of a single array ... I noticed fixdep uses ~2% of cpu time in kernel build, in function use_config() fixdep spends a lot of cpu cycles in linear searches in its internal string array. With about 400 stored strings per dep file, this begins to be noticeable. Convert fixdep to use a hash table. kbuild results on my x86_64 allmodconfig Before patch : real 10m30.414s user 61m51.456s sys 8m28.200s real 10m12.334s user 61m50.236s sys 8m30.448s real 10m42.947s user 61m50.028s sys 8m32.380s After: real 10m8.180s user 61m22.506s sys 8m32.384s real 10m35.039s user 61m21.654s sys 8m32.212s real 10m14.487s user 61m23.498s sys 8m32.312s Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>		2010-11-11 17:12:06 +01:00
