xfs: use current->journal_info for detecting transaction recursion
Because the iomap code using PF_MEMALLOC_NOFS to detect transaction recursion in XFS is just wrong. Remove it from the iomap code and replace it with XFS specific internal checks using current->journal_info instead. [djwong: This change also realigns the lifetime of NOFS flag changes to match the incore transaction, instead of the inconsistent scheme we have now.] Fixes: 9070733b ("xfs: abstract PF_FSTRANS to PF_MEMALLOC_NOFS") Signed-off-by:Dave Chinner <dchinner@redhat.com> Reviewed-by:
