Daisy chain end detection failed at least with older daisy chain devices that do not implement the last device signal. Signed-off-by:

Did not move the parport interface properly into IEEE1284_PH_REV_IDLE phase at end of data due to comparing bytes with nibbles. Internal phase IEEE1284_PH_HBUSY_DNA became unused, so remove it. Signed-off-by:

Fix potential buffer overflow in case the device ID did not end in semicolon. Also might fail to negotiate back to IEEE1284_MODE_COMPAT in case of failure. parport_device_id did not return what Documentation/parport-lowlevel.txt said, so I changed it to match it. Determining device ID length is overly complicated, but Tim Waugh recalled on linux-parport seeing some buggy device that might need it. Signed-off-by:

Previously invalid types were quietly changed to regular files, but at revalidation the inode was changed to bad. This was rather inconsistent behavior. Now check if the type is valid on initial lookup, and return -EIO if not. Signed-off-by:

In direct_io mode, send at least one page per reqest. Previously it was possible that reqests with zero data were sent, and hence the read/write didn't make any progress, resulting in an infinite (though interruptible) loop. Signed-off-by:

Make the maximum size of write data configurable by the filesystem. The previous fixed 4096 limit only worked on architectures where the page size is less or equal to this. This change make writing work on other architectures too, and also lets the filesystem receive bigger write requests in direct_io mode. Normal writes which go through the page cache are still limited to a page sized chunk per request. Signed-off-by:

Change the way a too large request is handled. Until now in this case the device read returned -EINVAL and the operation returned -EIO. Make it more flexibible by not returning -EINVAL from the read, but restarting it instead. Also remove the fixed limit on setxattr data and let the filesystem provide as large a read buffer as it needs to handle the extended attribute data. The symbolic link length is already checked by VFS to be less than PATH_MAX, so the extra check against FUSE_SYMLINK_MAX is not needed. The check in fuse_create_open() against FUSE_NAME_MAX is not needed, since the dentry has already been looked up, and hence the name already checked. Signed-off-by:

Add support for caching negative dentries. Up till now, ->d_revalidate() always forced a new lookup on these. Now let the lookup method return a zero node ID (not used for anything else) meaning a negative entry, but with a positive cache timeout. The old way of signaling negative entry (replying ENOENT) still works. Userspace should check the ABI minor version to see whether sending a zero ID is allowed by the kernel or not. Signed-off-by:

Add 'frsize' member to the statfs reply. I'm not sure if sending f_fsid will ever be needed, but just in case leave some space at the end of the structure, so less compatibility mess would be required. Signed-off-by:

- Removed some kmalloc's with __GFP_ZERO and replace it with memset() because it didn't work properly. - Fixed returned message frame in i2o_cfg_passthru() which caused raidutils to display wrong error message in case a disk was missing. - Fixed size of printk() in i2o_scsi.c. - Fixed get_device() and put_device() in probing of the I2O controller.

This patch introduces a struct subchannel_id containing the subchannel number (formerly referred to as "irq") and switches code formerly relying on the subchannel number over to it. While we're touching inline assemblies anyway, make sure they have correct memory constraints. Signed-off-by:

New feature V=V qdio pass-through. QDIO and HiperSockets processing in z/VM V=V guest environments (as well as V=R with z/VM running in LPAR mode) requires shadowing of all QDIO architecture queue elements. Especially the shadowing of SBALs and SLSBs structures in the hypervisor, and the need to issue SIGA SYNC operations to observe state changes, eventually causes significant CPU processing overhead in the hypervisor. The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O. Signed-off-by:
