Hi,
A proper patch series posting of the patch to skip inode dio counts where we don't need them. Performance results and general notes in patch #1. We can take this a bit further if we want to push this truncate locking into the caller, but I'd like to keep that as a separate patch series instead.
Changes since v2:
- Changed flag to DIO_SKIP_DIO_COUNT. Patch 2+3 will use this for skipping the extra inc/dec for btrfs and ext4, so better rename it to something that better tells what is happening in the deep mess that is dio.
- Have inode_dio_inc/dec() helpers. Again, this better tells the caller what is going on.
