Greeting. I was wondering if anyone is using AOP (Aspect Oriented Programming) to ensure login and authentication before allowing someone access to controllers and models. I found two versions of RCR 321 that discuss cut-based AOP, but as far as I can tell there isn''t an implementation of the RCR as an AOP framework. Additionally,...

Hi. I introduced "is_partially_uptodate" aops for OCFS2. A page can have multiple buffers and even if a page is not uptodate, some buffers can be uptodate on pagesize != blocksize environment. This aops checks that all buffers which correspond to a part of a file that we want to read are uptodate. If so, we do not have to issue actual rea...

...and so data copied to the page is lost. Fix the problem by invalidating page beyond EOF after failed write.

Hi, I did some more in-depth testing of OCFS2 quota code, especially with ECC feature enabled and spotted some problems. First four patches fix them. I need the fifth patch to be able to mount OCFS2 filesystem with 2.6.31-rc3. The sixth patch fixes a potential problem when quota syncing interval is updated while the cluster is running (which is not possible currently). Joel, could you please

The patch was created against a 1.4 tree. However, it applies cleanly to mainline too. The patch has been lightly tested. I am running fill_verify_holes on a non sparse volume currently. Please review. Sunil

As I understand an architecture of LLVM, we can inject some code after basic compilation. I need your advice or help in creating this kind of stuff. Perfect solution was, some "special" language that can produce LLVM bytecode, and some "Weaver" to integrate this 2 flow of code.

Hey folks I am just investigating using Aspects for logging my main Javascript "interfaces". I don''t believe Prototype has any built in capabilities for this but I just thought I''d check and see how people had tackled this before. I am still getting to grips with core JS so apologies if this is easy or obvious.. I am Googling as we speak also.. Cheers Matt

Mark and Joel, I found two serious bugs about xattr and inline-data. the first bug: in ocfs2_mknod(), we check and found the ACL or security xattr entry could be set into inode in ocfs2_calc_xattr_init(), then don't reserve block for them. But in ocfs2_mknod_locked(), if we found ocfs2 support inline-data, then set id_count with the max_inline_data. After that, we set acl/security xattr

One line fix from Joel's version. Also, some comments removed. 18:58 <sunil> wc->w_first_new_cpos = 18:58 <sunil> - ocfs2_align_bytes_to_clusters(inode->i_sb, i_size_read(inode)); 18:58 <sunil> + ocfs2_clusters_for_bytes(inode->i_sb, i_size_read(inode));
