      ocfs2: Remove obscure error handling in direct_write. · 95fa859a
      Tao Ma authored
      In ocfs2, actually we don't allow any direct write pass i_size,
      see the function ocfs2_prepare_inode_for_write. So we don't
      need the bogus simple_setsize.

      ocfs2: Add some trace log for orphan scan. · 3c3f20c9
      Tao Ma authored
      Now orphan scan worker has no trace log, so it is
      very hard to tell whether it is finished or blocked.
      So add 2 mlog trace log so that we can tell whether
      the current orphan scan worker is blocked or not.
      It does help when I analyzed a orphan scan bug.

      Ocfs2: Add new OCFS2_IOC_INFO ioctl for ocfs2 v8. · ddee5cdb
      Tristan Ye authored
      The reason why we need this ioctl is to offer the none-privileged
      end-user a possibility to get filesys info gathering.
      
      We use OCFS2_IOC_INFO to manipulate the new ioctl, userspace passes a
      structure to kernel containing an array of request pointers and request
      count, such as,
      
      * From userspace:
      
      struct ocfs2_info_blocksize oib = {
              .ib_req = {
                      .ir_magic = OCFS2_INFO_MAGIC,
                      .ir_code = OCFS2_INFO_BLOCKSIZE,
                      ...
              }
              ...
      }
      
      struct ocfs2_info_clustersize oic = {
              ...
      }
      
      uint64_t reqs[2] = {(unsigned long)&oib,
                          (unsigned long)&oic};
      
      struct ocfs2_info info = {
              .oi_requests = reqs,
              .oi_count = 2,
      }
      
      ret = ioctl(fd, OCFS2_IOC_INFO, &info);
      
      * In kernel:
      
      Get the request pointers from *info*, then handle each request one bye one.
      
      Idea here is to make the spearated request small enough to guarantee
      a better backward&forward compatibility since a small piece of request
      would be less likely to be broken if filesys on raw disk get changed.
      
      Currently, the following 7 requests are supported per the requirement from
      userspace tool o2info, and I believe it will grow over time:-)
      
              OCFS2_INFO_CLUSTERSIZE
              OCFS2_INFO_BLOCKSIZE
              OCFS2_INFO_MAXSLOTS
              OCFS2_INFO_LABEL
              OCFS2_INFO_UUID
              OCFS2_INFO_FS_FEATURES
              OCFS2_INFO_JOURNAL_SIZE
      
      This ioctl is only specific to OCFS2.
