BTW, another issue that I am seeing for a long time affects the fs-cache: When I use cache=mmap then things seem to be harmless, I periodically see messages like these, but that's about it:
[90763.435562] FS-Cache: Duplicate cookie detected [90763.436514] FS-Cache: O-cookie c=00dcb42f [p=00000003 fl=216 nc=0 na=0] [90763.437795] FS-Cache: O-cookie d=0000000000000000{?} n=0000000000000000 [90763.440096] FS-Cache: O-key=[8] 'a7ab2c0000000000' [90763.441656] FS-Cache: N-cookie c=00dcb4a7 [p=00000003 fl=2 nc=0 na=1] [90763.446753] FS-Cache: N-cookie d=000000005b583d5a{9p.inode} n=00000000212184fb [90763.448196] FS-Cache: N-key=[8] 'a7ab2c0000000000'
The real trouble starts when I use cache=loose though, in this case I get all sorts of misbehaviours from time to time, especially complaining about invalid file descriptors.
Any clues?
Best regards, Christian Schoenebeck
