The purpose of this patch set is the removal of grp->alloc_sem locks from block allocation paths. This resulting code is cleaner and should perform better in concurrent allocating tasks workloads. I ran several xfstests runs with these patches (4K block only). I tried several online resizes and verifyed that both in-core and on-disk group counters are correct. ext4: move ext4_add_groupblocks() to mballoc.c ext4: implement ext4_add_groupblocks() by freeing blocks ext4: synchronize ext4_mb_init_group() with buddy page lock ext4: teach ext4_mb_init_cache() to skip uptodate buddy caches ext4: remove alloc_semp -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
