Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have
