This was fixed in commit 0637c6f, but as a result the\nover-estimation by ext4_calc_metadata_amount() would lead to reserving\n2-3 times the number of pending delayed allocation blocks as\npotentially required metadata blocks.

The root cause of this BUG() was caused by the fact\nthat ext4_calc_metadata_amount() can severely over-estimate how many\nmetadata blocks will be needed, especially when using direct\nblock-mapped files.\n\nIn addition, it can also badly *under* estimate how much space is\nneeded, since ext4_calc_metadata_amount() assumes that the blocks are\ncontiguous, and this is not always true. If the application is\nwriting blocks to a sparse file, the number of metadata blocks\nnecessary can be severly underestimated by the functions\next4_da_reserve_space(), ext4_da_update_reserve_space() and\next4_da_release_space(). This was the cause of the dq_claim_space\nreports found on kerneloops.org.\n\nUnfortunately, doing this right means that we need to massively\nover-estimate the amount of free space needed.

Sorry, badly\n out-of-order cherry-pick from old queue.\n\n PS: there\u0027s a large pending series reworking the refcounting and\n lifetime rules for vfsmounts that will, among other things, allow to\n rip a subtree away _without_ dissolving connections in it, to be\n garbage-collected when all active references are gone. It\u0027s\n considerably saner wrt \"is the subtree busy\" logics, but it\u0027s nowhere\n near being ready for merge at the moment; this changeset is one of the\n things becoming possible with that sucker, but it certainly shouldn\u0027t\n have been picked during this cycle. My apologies...\"\n\nNoticed-by: Eric Paris \u003ceparis@redhat.com\u003e\nRequested-by: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "3a1abec9f6880cf406593c392636199ea1c6c917" }
