SVN rev 218175 on 2011-02-01 18:21:45Z by jhb
- Set the next_alloc fields for an i-node after allocating a new block
so that future allocations start with most recently allocated block
rather than the beginning of the filesystem.
- Fix ext2_alloccg() to properly scan for 8 block chunks that are not
aligned on 8-bit boundaries. Previously this was causing new blocks
to be allocated in a highly fragmented fashion (block 0 of a file at
lbn N, block 1 at lbn N + 8, block 2 at lbn N + 16, etc.).
- Cosmetic tweaks to the currently-disabled fancy realloc sysctls.
