Hi Eryu, my attempts at reproducing this are still not very reliable, someimes it takes three iterations, sometimes it's doing fine for 100+. Can you try reverting commit 0af32fb46 ("xfs: fix bogus space reservation in xfs_iomap_write_allocate") and give this a spin on your test setup? I wonder if somehow our accounting for the case where we convert from inline extents to the btree format is not correct, and the code before that commit was papering over that fact. -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
