Don't bother zeroing the page if it's already a hole under there.
We can save one allocation from this.

We should look at path-slots[0] rather than path-slots[0]+1 while trying to
merge with the hole behind us.
Also this patch will delete the the latter one if we can merge with both front
and back, leaving one hole covers all three.

sorry for the late reply, I can hardly to find time look at this.
However for an extent that is smaller than the specified

blkdev_issue_discard.
This won't affect the return value of fstrim on the drives without DISCARD,
because we've already checked that in btrfs_ioctl_fitrim, Thanks

Changelog V4:
*make btrfs_map_block() return full mapping.
Changelog V3:
*fix
We take an free extent out from allocator, trim it, then put it back,
but before we trim the block group, we should make sure the block group is
cached, so plus a little change to make cache_block_group() run without a
transaction.

btrfs_map_block() will only return a single stripe length, but we want the
full extent be mapped to each disk when we are trimming the extent,
so we add length to btrfs_bio_stripe and fill it if we are mapping for
REQ_DISCARD.

Dear list,
This is V4 of batched discard support, now we will get full mapping of
the free space on each device for RAID0/1/10/DUP instead of just a single
stripe length, and tested with xfsstests 251, Thanks.
Changelog V4:
*make btrfs_map_block() return full mapping.
Changelog V3:
*fix
Make the function public as we should update the reserved extents calculations
after taking out an extent for trimming.

Have a look at line 998, ioctl.c, inside btrfs_ioctl_clone(),
the src-i_size(the size of the testfile created by touch) is just 0, and this
will cause btrfs_ioctl_clone just return -EINVAL.
I'm not sure if it makes sense to clone a file which actually doesn't have any
data extents.
