[patch 00/19] Page cache: Replace PAGE_CACHE_xx with inline functions V2

This patchset cleans up page cache handling by replacing open coded shifts and adds with inline function calls. The ultimate goal is to replace all uses of PAGE_CACHE_xxx in the kernel through the use of these functions. All the functions take a mapping parameter. The mapping parameter is required

[RFC] support multiple max offset limits for a single superblock

Reiserfs, and now ext4, both have the possibility of encountering older on-disk format files which do not support the s_maxbytes of the newer formats. Reiserfs currently has spots in various places to catch these too-large offsets and reject them, but it's replicating a bit of code in the process.
