hole or a page beyond the\ninode size), so it requires slightly bigger budget, because we have\nto account the indexing size increase. And this flag basically\ntells that the budget for this page has to be \"new page budget\".\nThe \"new page budget\" is slightly bigger than the \"existing page\nbudget\".\n\nThe \u0027do_readpage()\u0027 function has the following assertion which\nsometimes is hit: \u0027ubifs_assert(!PageChecked(page))\u0027. Obviously,\nthe meaning of this assertion is: \"I should not be asked to read\na page which does not exist on the media\".\n\nHowever, in \u0027ubifs_write_begin()\u0027 we have a small \"trick\". Notice,\nthat VFS may write pages which were not read yet, so the page data\nwere not loaded from the media to the page cache yet. If VFS tells\nthat it is going to change only some part of the page, we obviously\nhave to load it from the media. However, if VFS tells that it is\ngoing to change whole page, we do not read it from the media for\noptimization purposes.\n\nHowever, since we do not read it, we do not know if it exists on\nthe media or not (a hole, etc). So we set the \u0027PG_checked\u0027 flag\nto this page to force bigger budget, just in case.\n\nSo \u0027ubifs_write_begin()\u0027 sets \u0027PG_checked\u0027. Then we are in\n\u0027ubifs_write_end()\u0027. And VFS tells us: \"hey, for some reasons I\nchanged my mind and did not change whole page\". Frankly, I do not\nknow why this happens, but I hit this somehow on an ARM platform.\nAnd this is extremely rare.\n\nSo in this case UBIFS does the following:\n\n1. Cancels allocated budget.\n2. Loads the page from the media by calling \u0027do_readpage()\u0027.\n3. Asks VFS to repeat the whole write operation from the very\n beginning (call \u0027-\u003ewrite_begin() again, etc).\n\nAnd the assertion warning is hit at the step 2 - remember we have\nthe \u0027PG_checked\u0027 set for this page, and \u0027do_readpage()\u0027 does not\nlike this. So this patch fixes the problem by adding step 1.5 and\ncleaning the \u0027PG_checked\u0027 before calling \u0027do_readpage()\u0027.\n\nAll in all, this patch does not fix any functionality issue, but it\nsilences UBIFS false positive warning which may happen in very very\nrare cases.\n\nAnd while on it, this patch also improves a commentary which explains\nthe reasons of setting the \u0027PG_checked\u0027 flag for the page. The old\ncommentary was a bit difficult to understand.\n\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\n" }, { "commit": "9d523cafbe0dab5a2b873ecd85c37fec9d1368f3", "tree": "b9555d625c0c9fb6e7036e28f53eef7b118513b3", "parents": [ "fc5e58c0c4fd86881ec8ba8e46e41a07e25dc7a6" ], "author": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Mon Mar 21 16:16:29 2011 +0200" }, "committer": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Thu Mar 24 16:16:08 2011 +0200" }, "message": "UBIFS: kill CONFIG_UBIFS_FS_DEBUG_CHKS\n\nSimplify UBIFS configuration menu and kill the option to enable self-check\ncompile-time.
