I'm pretty sure running XFS defrag will defrag without trimming no matter the type of block device.

Edit: yea you might actually be right. I Played with my fstab too much years ago, and never thought of that untill now

I understood that XFS automatically mounted SSD's with XFS_XFLAG_NODEFRAG set? Is this not the case?

But does that flag affect manually running xfs_fsr?

According to the man(8) page, it will avoid touching any blocks that have the chattr -f flag set, which is XSR_XFLAGS_NODEFRAG... So I think if the docs are still accurate to the code, yes.

A lot of ifs in that assumption.
