First, it\nprovides creators (devices and filesystems) of a backing_dev_info a flag\nthat declares whether or not it is necessary to ensure that page\ncontents cannot change during writeout. It is no longer assumed that\nthis is true of all devices (which was never true anyway). Second, the\nflag is used to relaxed the wait_on_page_writeback calls so that wait\nonly occurs if the device needs it. Third, it fixes up the remaining\ndisk-backed filesystems to use this improved conditional-wait logic to\nprovide stable page writes on those filesystems.\n\nIt is hoped that (for people not using checksumming devices, anyway)\nthis patchset will give back unnecessary performance decreases since the\noriginal stable page write patchset went into 3.0. Sorry about not\nfixing it sooner.\n\nComplaints were registered by several people about the long write\nlatencies introduced by the original stable page write patchset.\nGenerally speaking, the kernel ought to allocate as little extra memory\nas possible to facilitate writeout, but for people who simply cannot\nwait, a second page stability strategy is (re)introduced: snapshotting\npage contents. The waiting behavior is still the default strategy; to\nenable page snapshotting, a superblock flag (MS_SNAP_STABLE) must be\nset. This flag is used to bandaid^Henable stable page writeback on\next3[1], and is not used anywhere else.\n\nGiven that there are already a few storage devices and network FSes that\nhave rolled their own page stability wait/page snapshot code, it would\nbe nice to move towards consolidating all of these. It seems possible\nthat iscsi and raid5 may wish to use the new stable page write support\nto enable zero-copy writeout.\n\nThank you to Jan Kara for helping fix a couple more filesystems.\n\nPer Andrew Morton\u0027s request, here are the result of using dbench to measure\nlatencies on ext2:\n\n3.8.0-rc3:\n Operation Count AvgLat MaxLat\n ----------------------------------------\n WriteX 109347 0.028 59.817\n ReadX 347180 0.004 3.391\n Flush 15514 29.828 287.283\n\n Throughput 57.429 MB/sec 4 clients 4 procs max_latency\u003d287.290 ms\n\n3.8.0-rc3 + patches:\n WriteX 105556 0.029 4.273\n ReadX 335004 0.005 4.112\n Flush 14982 30.540 298.634\n\n Throughput 55.4496 MB/sec 4 clients 4 procs max_latency\u003d298.650 ms\n\nAs you can see, for ext2 the maximum write latency decreases from ~60ms\non a laptop hard disk to ~4ms. I\u0027m not sure why the flush latencies\nincrease, though I suspect that being able to dirty pages faster gives\nthe flusher more work to do.\n\nOn ext4, the average write latency decreases as well as all the maximum\nlatencies:\n\n3.8.0-rc3:\n WriteX 85624 0.152 33.078\n ReadX 272090 0.010 61.210\n Flush 12129 36.219 168.260\n\n Throughput 44.8618 MB/sec 4 clients 4 procs max_latency\u003d168.276 ms\n\n3.8.0-rc3 + patches:\n WriteX 86082 0.141 30.928\n ReadX 273358 0.010 36.124\n Flush 12214 34.800 165.689\n\n Throughput 44.9941 MB/sec 4 clients 4 procs max_latency\u003d165.722 ms\n\nXFS seems to exhibit similar latency improvements as ext2:\n\n3.8.0-rc3:\n WriteX 125739 0.028 104.343\n ReadX 399070 0.005 4.115\n Flush 17851 25.004 131.390\n\n Throughput 66.0024 MB/sec 4 clients 4 procs max_latency\u003d131.406 ms\n\n3.8.0-rc3 + patches:\n WriteX 123529 0.028 6.299\n ReadX 392434 0.005 4.287\n Flush 17549 25.120 188.687\n\n Throughput 64.9113 MB/sec 4 clients 4 procs max_latency\u003d188.704 ms\n\n...and btrfs, just to round things out, also shows some latency\ndecreases:\n\n3.8.0-rc3:\n WriteX 67122 0.083 82.355\n ReadX 212719 0.005 2.828\n Flush 9547 47.561 147.418\n\n Throughput 35.3391 MB/sec 4 clients 4 procs max_latency\u003d147.433 ms\n\n3.8.0-rc3 + patches:\n WriteX 64898 0.101 71.631\n ReadX 206673 0.005 7.123\n Flush 9190 47.963 219.034\n\n Throughput 34.0795 MB/sec 4 clients 4 procs max_latency\u003d219.044 ms\n\nBefore this patchset, all filesystems would block, regardless of whether\nor not it was necessary. ext3 would wait, but still generate occasional\nchecksum errors. The network filesystems were left to do their own\nthing, so they\u0027d wait too.\n\nAfter this patchset, all the disk filesystems except ext3 and btrfs will\nwait only if the hardware requires it. ext3 (if necessary) snapshots\npages instead of blocking, and btrfs provides its own bdi so the mm will\nnever wait. Network filesystems haven\u0027t been touched, so either they\nprovide their own wait code, or they don\u0027t block at all. The blocking\nbehavior is back to what it was before 3.0 if you don\u0027t have a disk\nrequiring stable page writes.\n\nThis patchset has been tested on 3.8.0-rc3 on x64 with ext3, ext4, and\nxfs. I\u0027ve spot-checked 3.8.0-rc4 and seem to be getting the same\nresults as -rc3.\n\n[1] The alternative fixes to ext3 include fixing the locking order and\npage bit handling like we did for ext4 (but then why not just use\next4?), or setting PG_writeback so early that ext3 becomes extremely\nslow. I tried that, but the number of write()s I could initiate dropped\nby nearly an order of magnitude. That was a bit much even for the\nauthor of the stable page series! :)\n\nThis patch:\n\nCreates a per-backing-device flag that tracks whether or not pages must\nbe held immutable during writeout. Eventually it will be used to waive\nwait_for_page_writeback() if nothing requires stable pages.\n\nSigned-off-by: Darrick J.

The reason is that that an\nunoptimized build can\u0027t always remove calls to an error-attributed\nfunction call (like we are using) that should effectively become dead\ncode if it were optimized.
