|
|
* 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,
|
|
* if the memory needed for the contiguous array ever becomes a problem,
|
|
* it is possible that a third level of indirection may be required.
