Re: [PATCH 1/1] xfs: enable FITRIM on the realtime device

[Konst Mayer <cdlscpmv@xxxxxxxxx>]

Hi Darrick,

We were able to reproduce the bug recently. Below is the script that did it:

    #!/bin/sh

    fallocate /mnt/file1 -l $((1024*1024*1024*1024*11))
    fallocate /mnt/file2 -l $((1024*1024*1024*1024*11))

    truncate -s 0 /mnt/file2
    rm /mnt/file2
    xfs_spaceman -c 'prealloc -s' /mnt
    fstrim /mnt -v

The output of fstrim showed that the realtime partition hadn't been trimmed.

I've attached two reports to this mail (short and full). Please take a look. 

Thanks,
Konst
