[ 3078.009563] BUG: Bad page state in process telegram-deskto pfn:65f4bd [ 3078.009563] page:ffffcf63d97d2f40 refcount:1 mapcount:0 mapping:ffff94009080d838 index:0x18f [ 3078.009565] fuse_file_aops [fuse] name:"domecamctl" [ 3078.009566] flags: 0x17ffffc0000034(uptodate|lru|active) [ 3078.009567] raw: 0017ffffc0000034 dead000000000100 dead000000000122 ffff94009080d838 [ 3078.009568] raw: 000000000000018f 0000000000000000 00000001ffffffff ffff93fbc7d10000 [ 3078.009568] page dumped because: page still charged to cgroup [ 3078.009568] page->mem_cgroup:ffff93fbc7d10000 [ 3078.009569] bad because of flags: 0x30(lru|active)

So the page still has flags as being active on (file) LRU list, despite(?) that FUSE open(2) attempts to free it. I'm not familiar how FUSE manages the page cache but here it seems to me it somehow mismatched it (or it releases pages not exclusive to it). (The memcg reason is not so specific in this case, since it's the last reason to be written in free_pages_check_bad().) Luis, back to you :-p -- You are receiving this mail because: You are on the CC list for the bug.
