Pull DAX updates part three from Darrick Wong: "Now that the xfs changes have landed, this third piece changes the FS_XFLAG_DAX ioctl code in xfs to request that the inode be reloaded after the last program closes the file, if doing so would make a S_DAX change happen.

I measured a 50% throughput regression for large direct writes. The observed on-the-wire behavior is that the client sends every NFS WRITE twice: once as an UNSTABLE WRITE plus a COMMIT, and once as a FILE_SYNC WRITE. This is because the nfs_write_match_verf() check in nfs_direct_commit_complete() fails for every WRITE. Buffered writes use nfs_write_completion(), which sets req->wb_verf correctly. Direct writes use nfs_direct_write_completion(), which does not set req->wb_verf at all. This leaves req->wb_verf set to all zeroes for every direct WRITE, and thus nfs_direct_commit_completion() always sets NFS_ODIRECT_RESCHED_WRITES. This fix appears to restore nearly all of the lost performance.

Use the following command to test nfsv4(size of file1M is 1MB): mount -t nfs -o vers=4.0,actimeo=60 127.0.0.1/dir1 /mnt cp file1M /mnt du -h /mnt/file1M -->0 within 60s, then 1M When write is done(cp file1M /mnt), will call this: nfs_writeback_done nfs4_write_done nfs4_write_done_cb nfs_writeback_update_inode nfs_post_op_update_inode_force_wcc_locked(change, ctime, mtime nfs_post_op_update_inode_force_wcc_locked nfs_set_cache_invalid nfs_refresh_inode_locked nfs_update_inode nfsd write response contains change, ctime, mtime, the flag will be clear after nfs_update_inode. Howerver, write response does not contain space_used, previous open response contains space_used whose value is 0, so inode->i_blocks is still 0. nfs_getattr -->called by "du -h" do_update |= force_sync || nfs_attribute_cache_expired -->false in 60s cache_validity = READ_ONCE(NFS_I(inode)->cache_validity) do_update |= cache_validity & (NFS_INO_INVALID_ATTR -->false if (do_update) { __nfs_revalidate_inode } Within 60s, does not send getattr request to nfsd, thus "du -h /mnt/file1M" is 0.

Avoid unnecessary cache sloshing by placing the buffer size estimation update logic behind an atomic bit flag. The size of GSS information included in each wrapped Reply does not change during the lifetime of a GSS context. Therefore, the au_rslack and au_ralign fields need to be updated only once after establishing a fresh GSS credential. Thus a slack size update must occur after a cred is created, duplicated, renewed, or expires. I'm not sure I have this exactly right. A trace point is introduced to track updates to these variables to enable troubleshooting the problem if I missed a spot.

Some apcs mailbox devices supports a clock driver, the compatible strings of devices supporting clock driver along with the clock driver name are maintained in a separate structure within the mailbox driver. And the clock driver is added based on device match. With increase in number of devices supporting the clock feature move the clock driver name inside the driver data. so that we can use a single API to get the register offset of mailbox driver and clock driver name together, and the clock driver will be added based on the driver data.
