This reverts commit c45653c341f5c8a0ce19c8f0ad4678640849cb86 because
sb_getblk_gfp is not really needed as
sb_getblk
  __getblk_gfp
    __getblk_slow
      grow_buffers
        grow_dev_page
	  gfp_mask = mapping_gfp_constraint(inode->i_mapping, ~__GFP_FS) | gfp

so __GFP_FS is cleared unconditionally and therefore the above commit
didn't have any real effect in fact.

This patch should not introduce any functional change. The main point
of this change is to reduce explicit GFP_NOFS usage inside ext4 code to
make the review of the remaining usage easier.

If I'm not mistaken, this patch is not dependent on any of the other
patches in this series (and the other patches are not dependent on
this one).  Hence, I could take this patch via the ext4 tree, correct?

Yes, that is correct
