Frankly I''m losing tolerance for the MS "stack." And I''m intrigued by Rails. But in my outfit I''m not only the web person, but also the application person and the DBA. So when I read that Rails doesn''t want to handle things like "compound keys" I blew right by those claims, thinking, "no way." But before I go deeper, I

In the spirit of the (long-term) intent to migrate away from the SelectionDAG framework, it is desirable to implement legalization passes as discrete passes. Attached is a patch which implements the beginning of a new type legalization pass, to help motivate discussion. Is LLVM IR the right level for this? The main alternative approach that's been discussed is to do FastISel to a

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

Hi all, Change from v1 to v2: bug fix and metadata/credits reservation improvement. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.
