We already rely on the fact that the sync code will cause a synchronous log force later on (currently via xfs_fs_sync_fs -> xfs_quiesce_data -> xfs_sync_data), so no need to do this here. This allows us to avoid a lot of synchronous log forces during sync, which pays of especially with delayed logging enabled. Some compilebench numbers that show this: xfs (delayed logging, 256k logbufs) =================================== intial create 25.94 MB/s 25.75 MB/s 25.64 MB/s create 8.54 MB/s 9.12 MB/s 9.15 MB/s patch 2.47 MB/s 2.47 MB/s 3.17 MB/s compile 29.65 MB/s 30.51 MB/s 27.33 MB/s clean 90.92 MB/s 98.83 MB/s 128.87 MB/s read tree 11.90 MB/s 11.84 MB/s 8.56 MB/s read compiled 28.75 MB/s 29.96 MB/s 24.25 MB/s delete tree 8.39 seconds 8.12 seconds 8.46 seconds delete compiled 8.35 seconds 8.44 seconds 5.11 seconds stat tree 6.03 seconds 5.59 seconds 5.19 seconds stat compiled tree 9.00 seconds 9.52 seconds 8.49 seconds xfs + write_inode log_force removal =================================== intial create 25.87 MB/s 25.76 MB/s 25.87 MB/s create 15.18 MB/s 14.80 MB/s 14.94 MB/s patch 3.13 MB/s 3.14 MB/s 3.11 MB/s compile 36.74 MB/s 37.17 MB/s 36.84 MB/s clean 226.02 MB/s 222.58 MB/s 217.94 MB/s read tree 15.14 MB/s 15.02 MB/s 15.14 MB/s read compiled tree 29.30 MB/s 29.31 MB/s 29.32 MB/s delete tree 6.22 seconds 6.14 seconds 6.15 seconds delete compiled tree 5.75 seconds 5.92 seconds 5.81 seconds stat tree 4.60 seconds 4.51 seconds 4.56 seconds stat compiled tree 4.07 seconds 3.87 seconds 3.96 seconds In addition to that also remove the delwri inode flush that is unessecary now that bulkstat is always coherent.
