linux-next: xfs metadata corruption since 30 March

From: Qian Cai
Date: Tue Mar 31 2020 - 17:57:30 EST

Ever since two days ago, linux-next starts to trigger xfs metadata corruption
during compilation workloads on both powerpc and arm64,

I suspect it could be one of those commits,

https://lore.kernel.org/linux-xfs/20200328182533.GM29339@magnolia/

Especially, those commits that would mark corruption more aggressively?

[8d57c21600a5] xfs: add a function to deal with corrupt buffers post-verifiers
[e83cf875d67a] xfs: xfs_buf_corruption_error should take __this_address

[1cb5deb5bc09] xfs: don't ever return a stale pointer from __xfs_dir3_free_read
[6fb5aac73310] xfs: check owner of dir3 free blocks
[a10c21ed5d52] xfs: check owner of dir3 data blocks
