Hi,
I'm using kernel v4.19.y and find that v4.19.y fails in the latest
xfstests generic/075, 091, 112, 127 and 263, which can be simply
reproduced as follows:
# kernel 4.19.y
$ xfs_io -fc "copy_range -s 0 -d 1 -l 1 /mnt/nfs/file" /mnt/nfs/file
copy_range: Invalid argument
# kernel 5.1.0
$ xfs_io -fc "copy_range -s 0 -d 1 -l 1 /mnt/nfs/file" /mnt/nfs/file
# success
I notice that upstream (v5.1+) has already fixed this issue with:
1) commit 45ac486ecf2dc998e25cf32f0cabf2deaad875be
2) commit 0769663b4f580566ef6cdf366f3073dbe8022c39
But these patches do not cc stable@vger.kernel.org (why? forgotten?).
And will v4.19.y consider to backport these patches?
Thanks,
Yu
