XFS project quota treats project hierarchies as "mini filesysems" and
so rather than -EDQUOT, the intent is to return -ENOSPC when a quota
reservation fails, but this behavior is not consistent.
The only place we make a decision between -EDQUOT and -ENOSPC
returns based on quota type is in xfs_trans_dqresv().
This behavior is currently controlled by whether or not the
XFS_QMOPT_ENOSPC flag gets passed into the quota reservation. However,
its use is not consistent; paths such as xfs_create() and xfs_symlink()
don't set the flag, so a reservation failure will return -EDQUOT for
project quota reservation failures rather than -ENOSPC for these sorts
of operations, even for project quota:
# mkdir mnt/project
# xfs_quota -x -c "project -s -p mnt/project 42" mnt
# xfs_quota -x -c 'limit -p isoft=2 ihard=3 42' mnt
# touch mnt/project/file{1,2,3}
touch: cannot touch ‘mnt/project/file3’: Disk quota exceeded
We can make this consistent by not requiring the flag to be set at the
top of the callchain; instead we can simply test whether we are
reserving a project quota with XFS_QM_ISPDQ in xfs_trans_dqresv and if
so, return -ENOSPC for that failure. This removes the need for the
XFS_QMOPT_ENOSPC altogether and simplifies the code a fair bit.

Widen the incore inode's i_delayed_blks counter to be a 64-bit integer.
This is necessary to fix an integer overflow problem that can be
reproduced easily now that we use the counter to track blocks that are
assigned to the inode in memory but not on disk. This includes actual
delalloc reservations as well as real extents in the COW fork that
are waiting to be remapped into the data fork.
These 'delayed mapping' blocks can easily exceed 2^32 blocks if one
creates a very large sparse file of size approximately 2^33 bytes with
one byte written every 2^23 bytes, sets a very large COW extent size
hint of 2^23 blocks, reflinks the first file into a second file, and
then writes a single byte every 2^23 blocks in the original file.
When this happens, we'll try to create approximately 1024 2^23 extent
reservations in the COW fork, which will overflow the counter and cause
problems.
Note that on x64 we end up filling a 4-byte gap in the structure so this
doesn't increase the incore size.
