Annotated. Original reused the structure that contained pointers into remapped iomem for storing offsets in such area, so we need to split that beast. Signed-off-by:

Use PIO code from ide-taskfile.c in ide-disk.c so: * drive status is checked after PIO read * request is failed if invalid data phase is detected during PIO write Signed-off-by:Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Merge multwrite_intr() into write_intr(). The only change in functionality is that rq->errors is now also cleared for multiwrite PIO (if there is no error). Signed-off-by: -

Convert CONFIG_IDE_TASKFILE_IO=n code to use scatterlists for PIO transfers. Fixes longstanding 'data integrity on error' issue and makes barriers work with PIO. Signed-off-by: -
Bartlomiej Zolnierkiewicz authored
Use scatterlists for taskfile based PIO transfers instead of directly walking rq->[bio,cbio] lists. If CONFIG_IDE_TASKFILE_IO is defined this code will be used for fs requests. ide_pio_sector() is based on ata_pio_sector() from libata-core.c so kudos to Jeff. Signed-off-by: -

Sometimes, it's useful to have locking. Especially when we're talking about time keeping. It would appear that shemminger's patch of 5th February 2003 completely missed updating _ANY_ ARM timer implementations and, because linux-arch didn't exist at the time, there appears to have been no notification to any architecture developer that maybe, just maybe, some work was required. One wonders how many other changes are in the kernel which architecture maintainers have missed.

- Ensure FIQs are enabled when cpu_idle() is called. - Remove unused members of irq_cpustat_t. - Remove unnecessary #ifndef CONFIG_SMP...#endif around irq_exit() macro. - Rename __stf/__clf such that it stresses that they affect only local state (as per local_irq_xxx). - Move THREAD_SIZE such that it can be used in current_thread_info()

The orphan list holds inodes that need to be truncated on recovery. In the O_DIRECT case, it's used if we extend the inode --- the truncate on recovery means we'll recover the newly-allocated disk blocks if we crash after the IO starts but before i_size is updated on disk. Now, the orphan list is *also* used to delete inodes that are unlinked but still-open. Those get truncated but also deleted on recovery. The orphan list is held both in memory and on disk. So the rules are that the inode can't be reclaimed while on the orphan list. There are only two cases --- either the inode is actively being written(O_DIRECT) or truncated (in which case the inode is by definition not going to be reused), or it's unlinked but still open (again, non-reclaimable). But in the case where you're truncating or write(O_DIRECT)ing a file that is *ALSO* unlinked, there's a problem --- the final unlink would put the inode on the orphan list, but the write/truncate would try to add/remove it. End result is that the inode disappears from the orphan list while it's still unlinked-but-in-use. That's just a leak-on-crash, it's not going to be detectable in normal use. But it's still a bug, and the way we fix it is for direct-IO and truncate not to do the ext3_orphan_del if the file is unlinked (ie. i_nlink==0). Signed-off-by:

The following patches provide an interface to the lease subsystem in the current VFS locking code. NFSv4 delegations and Samba op-locks share most architecture features. The version 4 NFS server delegation implementation should use leases to co-ordinate behavior between local, Samba, and NFS access. The main design points are - Seperate the fcntl interface from the file_lock FL_LEASE processing in fcntl_setlease, creating __setlease() called by fcntl_setlease() - Add new lock_manager callbacks to enable lease properties to be set, leases to be broken, and leases to be cleaned up: with default callbacks preserving the current fcntl_setlease properties. - Add a new interface, setlease() which also calls __setlease(), and remove_lease() for kernel lease managers (e.g. the v4 NFS server) This patch: Add a lock manager copy lock callback to locks_copy_lock() so that nfsd can set lease properties.
