I believe that they can be integrated with the mainline kernel. Hence I have posted them separately from the subpagesize-blocksize patchset. I have testsed the patchset by running xfstests on ppc64 and x86_64. On ppc64, some of the Btrfs specific tests and generic/255 fail because they assume 4K as the filesystem's block size. I have fixed some of the test cases. I will fix the rest and mail them to the fstests mailing list in the near future. Changes from V4: 1. Removed the RFC tag. Changes from V3: Two new issues have been been fixed by the patches, 1. Btrfs: prepare_pages: Retry adding a page to the page cache. 2. Btrfs: Return valid delalloc range when the page does not have PG_Dirty flag set or has been invalidated. IMHO, The above issues are also applicable to the "page size == block size" scenario but for reasons unknown to me they aren't seen even when the tests are run for a long time. Changes from V2: 1. For detecting logical errors, Use ASSERT() calls instead of calls to BUG_ON(). 2. In the patch "Btrfs: Compute and look up csums based on sectorsized blocks", fix usage of kmap_atomic/kunmap_atomic such that between the kmap_atomic() and kunmap_atomic() calls we do not invoke any function that might cause the current task to sleep. Changes from V1: 1. Call round_[down,up]() functions instead of doing hard coded alignment.
