The kernel commit xfs: fix inode fork extent count overflow
(3f8a4f1d876d3e3e49e50b0396eaffcc4ba71b08) mentions that 10 billion
data fork extents should be possible to create. However the
corresponding on-disk field has a signed 32-bit type. Hence this
commit extends the per-inode data extent counter to 47 bits. The
length of 47-bits was chosen because,
Maximum file size = 2^63.
Maximum extent count when using 64k block size = 2^63 / 2^16 = 2^47.
Also, XFS has a per-inode xattr extent counter which is 16 bits
wide. A workload which
1. Creates 1 million 255-byte sized xattrs,
2. Deletes 50% of these xattrs in an alternating manner,
3. Tries to insert 400,000 new 255-byte sized xattrs
causes the xattr extent counter to overflow.
Dave tells me that there are instances where a single file has more than
100 million hardlinks. With parent pointers being stored in xattrs, we
will overflow the signed 16-bits wide xattr extent counter when large
number of hardlinks are created. Hence this commit extends the on-disk
field to 32-bits.
The following changes are made to accomplish this,
1. A new incompat superblock flag to prevent older kernels from mounting
the filesystem. This flag has to be set during mkfs time.
2. Carve out a new 32-bit field from xfs_dinode->di_pad2[]. This field
holds the most significant 15 bits of the data extent counter.
3. Carve out a new 16-bit field from xfs_dinode->di_pad2[]. This field
holds the most significant 16 bits of the attr extent counter.
