From: Michal Hocko <mhocko@xxxxxxxx>
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.
