[PATCH 9/9] Revert "ext4: fix wrong gfp type under transaction"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michal Hocko <mhocko@xxxxxxxx>

This reverts commit 216553c4b7f3e3e2beb4981cddca9b2027523928. Now that
the transaction context uses memalloc_nofs_save and all allocations
within the this context inherit GFP_NOFS automatically, there is no
reason to mark specific allocations explicitly.

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.
