Freeing throttle should account for holes
Deletion throttle currently does not account for holes in a file. This means that it can activate when it shouldn't. To fix it we switch the throttle to be based on the number of L1 blocks we will have to dirty when freeing Reviewed by: Tom Caputi <[email protected]> Reviewed by: Matt Ahrens <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Alek Pinchuk <[email protected]> Closes #7725 Closes #7888
