sys_fs_stat' failed is related with issues in OS file system ?

In message log is displayed several times the lines below :

sys_ss_access_control_engine' failed with 0x80010003 : CELL_ENOSYS
'sys_fs_stat' failed with 0x80010006 : CELL_ENOENT, “/dev_hdd0/game/NPUA80918-DATA/USRDIR/ARCHIVES” [1]

The failed messages are related with the emulator or any problem in OS file system not allowing RPCS3 reads in some files ?

OS is Linux Ubuntu 20.04 64 bits.
Thanks for reply.

If you don't know how the original code is supposed to work these kind of messages are irrelevant. ENOENT return code is perfectly normal.

Thanks very much.
