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

86 * This is the xfs in-core inode structure.
87 * Most of the on-disk inode is embedded in the i_d field.
89 * The extent pointers/inline file space, however, are managed
90 * separately. The memory for this information is pointed to by
91 * the if_u1 unions depending on the type of the data.
92 * This is used to linearize the array of extents for fast in-core
93 * access. This is used until the file's number of extents
94 * surpasses XFS_MAX_INCORE_EXTENTS, at which point all extent pointers
95 * are accessed through the buffer cache.
97 * Other state kept in the in-core inode is used for identification,
98 * locking, transactional updating, etc of the inode.
