| H A D | Makefile | diff 221166 Thu Apr 28 12:31:45 MDT 2011 jhb 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.

| H A D | open.2 | diff 77115 Thu May 24 05:22:27 MDT 2001 dillon This patch implements O_DIRECT about 80% of the way. It takes a patchset Tor created a while ago, removes the raw I/O piece (that has cache coherency problems), and adds a buffer cache / VM freeing piece. Essentially this patch causes O_DIRECT I/O to not be left in the cache, but does not prevent it from going through the cache, hence the 80%. For the last 20% we need a method by which the I/O can be issued directly to buffer supplied by the user process and bypass the buffer cache entirely, but still maintain cache coherency. I also have the code working under -stable but the changes made to sys/file.h may not be MFCable, so an MFC is not on the table yet. Submitted by: tegge, dillon |
