- 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.
