234 | * Multiple writes at the end of the file must coordinate zp_size updates | |
235 | * to ensure data isn't lost. A compare and swap loop is currently used | |
236 | * to ensure the file size is at least the offset last written. | |
237 | * 3. For reads (zfs_read, zfs_get_data & zfs_putapage) just the range being | |
238 | * read needs to be locked as RL_READER. A check against zp_size can then | |
239 | * be made for reading beyond end of file. | |
