Version: 23.6-1
Severity: normal
Hi,
fuser(1) will call statx():
statx(0</dev/pts/1<char 136:1>>, "/", AT_STATX_DONT_SYNC|AT_NO_AUTOMOUNT,
STATX_TYPE|STATX_INO, 0x7fffb96603a0) = -1 ENOSYS (Function not implemented)
which is not avilable on kernels before, I think, 4.11.
When that fails, fuser(1) prints
"Cannot find socket's device number.
Cannot stat /: Invalid argument"
which is not helpful in finding out what's wrong.
I realize that Debian doesn't ship such old kernels anymore, but I think it
would be desirable to be more backwards compatible, and, failing that, to print
an error message that actually explains what went wrong.
To me it looks like it would be best to fall back to the older stat* calls if
statx() is not available at runtime.
A point could also be made to refuse installation/upgrade on kernels older than
4.11, or kernels that don't have statx, unless the user creates some flag file
to override this (e.g. because they don't need fuser(1)).
Best regards,
András
