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.
