We have a bug report in Debian[0] open that grub-probe is very slow due to the use of ioctl(BLKFLSBUF) A comment above it says this is needed due to a bug in the Linux kernel. Is there a safe way to check if this is still needed with a recent Kernel? This seems to be added 2003, so things could have changed now a bit.
