New XFS Programs Update Supports New XFS On-Disk Format

[xeekei]

I am a big fan of XFS, and it's my go to filesystem for most things. My /home is XFS, and all my extra storage hard drives is XFS. I've been thinking about going with an XFS /usr too. /boot is Ext2 though, and the root partition is Ext4. I love that I can pick and choose filesystems so freely in Linux.

Again, since ext4 is good with little files (like the ones created on /tmp while compiling anything), the performance difference is vast for me

If you're using the gcc family compilers, you really should look into the -pipe option. Or failing that, just put /tmp on a tmpfs. Or do both.

No and no. you have to reformat the partition with the xfsutils that support the v5 format, ie by passing -m crc=1 to mkfs.xfs

If I format the partition with this option, will I be able to mount it with a 3.12 kernel?

Checked. It does.
