Subject: xfs: ensure xfs_errortag_random_default matches XFS_ERRTAG_MAX
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b2c2974b8cdf1eb3ef90ff845eb27b19e2187b7e;p=linux.git

xfs: ensure xfs_errortag_random_default matches XFS_ERRTAG_MAX

Add the BUILD_BUG_ON to xfs_errortag_add() in order to make sure that
the length of xfs_errortag_random_default matches XFS_ERRTAG_MAX when
building.
