| * The following xfs_ext_irec_t struct introduces a second (top) level |
| * to the in-core extent allocation scheme. These structs are allocated |
| * in a contiguous block, creating an indirection array where each entry |
| * (irec) contains a pointer to a buffer of in-core extent records which |
| * it manages. Each extent buffer is 4k in size, since 4k is the system |
| * page size on Linux i386 and systems with larger page sizes don't seem |
| * to gain much, if anything, by using their native page size as the |
| * extent buffer size. Also, using 4k extent buffers everywhere provides |
| * a consistent interface for CXFS across different platforms. |
| * |
| * There is currently no limit on the number of irec's (extent lists) |
| * allowed, so heavily fragmented files may require an indirection array |
| * which spans multiple system pages of memory. The number of extents |
| * which would require this amount of contiguous memory is very large |
| * and should not cause problems in the foreseeable future. However, |

| * it is possible that a third level of indirection may be required. |
