Hi.
This patchset aims to remove most of XFS custom memory allocation mechanism and
replace it with generic memory interfaces. This includes:
- removing KM_* flags
- removing most of the kmem_* API, with the exception of 2 helpers (see the last
two patches).
All mem alloc requests using KM_* flags, were replaced following these rules:
- KM_ZONE_* flags were directly replaced by their SLAB_* relative
- KM_NOFS: Replaced by GFP_NOFS
- KM_MAYFAIL: Replaced by __GFP_RETRY_MAYFAIL
- All memalloc requests made with no KM_* flags, like:
kmem_alloc(item, 0);
Have been replaced by GFP_KERNEL.
- Every memalloc request without KM_MAYFAIL have been replaced by __GFP_NOFAIL
and the other flags OR'ed together.
These patches passed a few xfstests runs without issues.
Cheers
