..., I''m starting to set things up to move win32-open3 towards a pure Ruby solution. I''ve got a windows-pipe module setup, but now I need to define some of the msvcrt IO functions. However, I can''t find documentation on MSDN or my system for the following: FMODE_READABLE FMODE_WRITABLE FMODE_BINMODE MakeOpenFile() io_alloc() A recursive search on my header files didn''t reveal anything. Any ideas? Thanks, Dan This communication is the property of Qwest and may contain confidential or privileged information. Unauthorized use of this communication is strictly pr...

Hi, The following series of patches implements in btrfs an ioctl to do out-of-band deduplication of file extents. To be clear, this means that the file system is mounted and running, but the dedupe is not done during file writes, but after the fact when some userspace software initiates a dedupe. The primary patch is loosely based off of one sent by Josef Bacik back in January, 2011.

...nty = d_alloc_pseudo(movable_inode_mnt->mnt_sb, &this); patch.mnt = mntget(movable_inode_mnt); inode = new_inode(sb); .. .. inode->i_mapping->a_ops = a_ops; d_instantiate(path.dentry, inode); return alloc_file(&path, FMODE_WRITE | FMODE_READ, f_op); } And in our driver, we can change vma->vm_file with new one. int test_mmap(struct file *filp, struct vm_area_structd *vma) { struct file *newfile = movable_inode_getfile("[test"], filep->f_op, &test_aops);...

We're currently support two paths from VFS to preallocate unwritten extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of punching-hole should be treated as the same, this patch tries to teach file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2 is wise enough to do the rest of work;-) Signed-off-by: Tristan Ye <tristan.ye at oracle.com> --- fs/ioctl.c

Has anyone tried LFS (ie >2G files support) and Ext3 together? Are there good reasons why this should/should not work? I see the RH enterprise kernel patch set specifically does not attempt both lfs and ext3, but the lfs patches themselves touch some reasonably localised parts of ext2, so I would hope (without having dived in there to test), that the ext3 changes would mirror that
