Ernesto A. Fernández 7602aaf673 hfsplus: prevent btree data loss on ENOSPC 
[ Upstream commit d92915c35bfaf763d78bf1d5ac7f183420e3bd99 ]

Inserting or deleting a record in a btree may require splitting several of
its nodes.  If we hit ENOSPC halfway through, the new nodes will be left
orphaned and their records will be lost.  This could mean lost inodes,
extents or xattrs.

Henceforth, check the available disk space before making any changes.
This still leaves the potential problem of corruption on ENOMEM.

The patch can be tested with xfstests generic/027.
