xfs: support ability to wait on new inodes
Inodes that are inserted into the perag tree but still under construction are flagged with the XFS_INEW bit. Most contexts either skip such inodes when they are encountered or have the ability to handle them. The runtime quotaoff sequence introduces a context that must wait for construction of such inodes to correctly ensure that all dquots in the fs are released. In anticipation of this, support the ability to wait on new inodes. Wake the appropriate bit when XFS_INEW is cleared. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.
