Detailed Description

Follows a sqfs_inode_t if type is SQFS_INODE_EXT_FILE.

Follows a sqfs_inode_t if type is SQFS_INODE_FILE.

The declaration does not contain the flexible array member for the data block sizes because sqfs_inode_generic_t would otherwies be impossible to implement without violating the C standard.

For each data block, the inode is followed by a 32 bit integer that holds the on-disk size of the compressed block in bytes and has bit number 24 set if the block is stored uncompressed.

If a block size is specified as zero, it is assumed to be an entire block filled with zero bytes.
