Date: Thu, 17 Jan 2019 10:32:16 +0000 From: bugzilla-daemon@...zilla.kernel.org To: linux-ext4@...r.kernel.org Subject: [Bug 201631] WARNING: CPU: 11 PID: 29593 at fs/ext4/inode.c:3927 .ext4_set_page_dirty+0x70/0xb0 https://bugzilla.kernel.org/show_bug.cgi?id=201631 --- Comment #43 from Jan Kara (jack@...e.cz) --- Thanks for gathering the results and sorry for not replying earlier. I've been busy with other work... So again I can see in the logs: Clean page (index 137, ino 1820427, i_size 1144448, flags 3ffe0000002016) with dirty PTE (pte_val c0000005f899f186) on unmap! WARNING: CPU: 3 PID: 1532 at fs/ext4/inode.c:3935 .ext4_set_page_dirty+0x80/0x170 ... page 137: b_state 21, b_blocknr 2726281, b_mapped 0, b_cleaned 1498120697108, now 1498125595648 So the page has been submitted for writeout some 5 ms ago but still we didn't get b_mapped set at all which would mean that ext4_page_mkwrite() got never called for the page - which is very weird. I'll ponder more about it possibly come up with more debugging. -- You are receiving this mail because: You are watching the assignee of the bug.
