- 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.

free i-nodes or blocks to handle a race where another thread might have
allocated the last i-node or block while we were waiting for the buffer.

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.

Eliminate the i_devvp field from the incore inodes, we can get the same
value from ip->i_ump->um_devvp.

situation is normal for the forced unmount.

- Return EOPNOTSUPP before EROFS to be consistent with other filesystems.
- Fix setting of the nodump flag for users without PRIV_VFS_SYSFLAGS privilege.

- 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.
