SVN rev 219401 on 2011-03-08 17:27:36Z by jh
MFC r201773:
- Change the type of size_max to u_quad_t because its value is converted
with vfs_scanopt(9) using the "%qu" format string.
- Limit the maximum value of size_max to (SIZE_MAX - PAGE_SIZE) to
prevent overflow in howmany() macro.
PR: kern/141194
MFC r202187:
- Fix some style bugs in tmpfs_mount().
- Remove a stale comment about tmpfs_mem_info() 'total' argument.
MFC r202708:
- Change the type of nodes_max to u_int and use "%u" format string to
convert its value.
- Set default tm_nodes_max to min(pages + 3, UINT32_MAX). It's more
reasonable than the old four nodes per page (with page size 4096) because
non-empty regular files always use at least one page. This fixes possible
overflow in the calculation.
- Don't allow more than tm_nodes_max nodes allocated in tmpfs_alloc_node().
