Xfs and Ext* uses EFSCORRUPTED to indicate filesystem corruption.
They both map EFSCORRUPTED to EUCLEAN.
Btrfs/Ubifs/fscrypto all use EUCLEAN directly to indicate filesystem
corruption.
And block layer is going to distinguish filesystem corruption with
oridinary EIO error, it's a good idea to export the initial EFSCORRUPTED
declaration to <linux/errno.h> so all filesystems and block layer can
take advantage of this easier-to-read error number.
