1d04725a7a ext2fs: make some inode fields match the ext2 spec.
Ext2fs uses unsigned fields in its dinode struct.
FreeBSD can have negative values in some of those
fields and the inode is meant to interact with the
system so we have never respected the unsigned
nature of most of those fields.

Block numbers and the NFS generation number do
not need to be signed so redefine them as
unsigned to better match the on-disk information.

9e880b876d Sync with several changes in UFS/FFS:
- 77115: Implement support for O_DIRECT.
- 98425: Fix a performance issue introduced in 70131 that was causing
  reads before writes even when writing full blocks.
- 98658: Rename the BALLOC flags from B_* to BA_* to avoid confusion with
  the struct buf B_ flags.
- 100344: Merge the BA_ and IO_ flags so so that they may both be used in
  the same flags word. This merger is possible by assigning the IO_ flags
  to the low sixteen bits and the BA_ flags the high sixteen bits.
- 105422: Fix a file-rewrite performance case.
- 129545: Implement IO_INVAL in VOP_WRITE() by marking the buffer as
  "no cache".
- Readd the DOINGASYNC() macro and use it to control asynchronous writes.
  Change i-node updates to honor DOINGASYNC() instead of always being
  synchronous.
- Use a PRIV_VFS_RETAINSUGID check instead of checking cr_uid against 0
  directly when deciding whether or not to clear suid and sgid bits.

e09c00cada Bring in the ext2fs work done by Aditya Sarawgi during and after Google Summer
of Code 2009:

- BSDL block and inode allocation policies for ext2fs. This involves the use
  FFS1 style block and inode allocation for ext2fs. Preallocation was removed
  since it was GPL'd.
- Make ext2fs MPSAFE by introducing locks to per-mount datastructures.
- Fixes for kern/122047 PR.
- Various small bugfixes.
- Move out of gnu/ directory.
