When formatting an inode item, we have to allocate a separate buffer to hold extents when there are delayed allocation extents on the inode and it is in extent format. The allocation size is derived from the in-core data fork representation, which accounts for delayed allocation extents, while the on-disk representation does not contain any delalloc extents. As a result of this mismatch, the allocated buffer can be far larger than needed to hold the real extent list which, due to the fact the inode is in extent format, is limited to the size of the literal area of the inode. However, we can have thousands of delalloc extents, resulting in an allocation size orders of magnitude larger than is needed to hold all the real extents. Fix this by limiting the size of the buffer being allocated to the size of the literal area of the inodes in the filesystem (i.e. the maximum size an inode fork can grow to).
