faccessat2() and getxattr() syscall support missing
On Kernels >5.8 faccessat2() is used to check permissions and replaces faccessat. Therefore, commands such as rm fail.
some file systems also use getxattr() for each entry during ls -l which causes the following output:
❯ gkfs ls-l /tmp/gkfs_mountdir/ls: /tmp/gkfs_mountdir/largefile: No such file or directoryls: /tmp/gkfs_mountdir/testfile: No such file or directorytotal 0-rw-r--r-- 1 evie evie 734003200 Jan 1 1970 largefile-rw-rw-rw- 1 evie evie 0 Jan 1 1970 testfile
