2005-11-16[DVB]: Add compat ioctl handling.David S. Miller1-0/+133
Based upon a patch by Guido Guenther <agx@sigxcpu.org>. Some of these ioctls had embedded time_t objects or pointers, so needed translation. Signed-off-by: David S. Miller <davem@davemloft.net>

2005-11-13[PATCH] aio: remove kioctx from mm_structZach Brown1-18/+9
Sync iocbs have a life cycle that don't need a kioctx. Their retrying, if any, is done in the context of their owner who has allocated them on the stack. The sole user of a sync iocb's ctx reference was aio_complete() checking for an elevated iocb ref count that could never happen. No path which grabs an iocb ref has access to sync iocbs. If we were to implement sync iocb cancelation it would be done by the owner of the iocb using its on-stack reference. Removing this chunk from aio_complete allows us to remove the entire kioctx instance from mm_struct, reducing its size by a third. On a i386 testing box the slab size went from 768 to 504 bytes and from 5 to 8 per page.

2005-11-13[PATCH] VFS: Fix memory leak with file leasesJ. Bruce Fields1-1/+1
The patch http://linux.bkbits.net:8080/linux-2.6/diffs/fs/locks.c@1.70??nav=index.html introduced a pretty nasty memory leak in the lease code. When freeing the lease, the code in locks_delete_lock() will correctly clean up the fasync queue, but when we return to fcntl_setlease(), the freed fasync entry will be reinstated. This patch ensures that we skip the call to fasync_helper() when we're freeing up the lease. Signed-off-by: J.

2005-11-09[PATCH] sanitize lookup_hash prototypeChristoph Hellwig1-10/+10
->permission and ->lookup have a struct nameidata * argument these days to pass down lookup intents. Unfortunately some callers of lookup_hash don't actually pass this one down. For lookup_one_len() we don't have a struct nameidata to pass down, but as this function is a library function only used by filesystem code this is an acceptable limitation. All other callers should pass down the nameidata, so this patch changes the lookup_hash interface to only take a struct nameidata argument and derives the other two arguments to __lookup_hash from it. All callers already have the nameidata argument available so this is not a problem. At the same time I'd like to deprecate the lookup_hash interface as there are better exported interfaces for filesystem usage. Before it can actually be removed I need to fix up rpc_pipefs.

2005-11-09[PATCH] add a file_permission helperChristoph Hellwig6-19/+41
A few more callers of permission() just want to check for a different access pattern on an already open file. This patch adds a wrapper for permission() that takes a file in preparation of per-mount read-only support and to clean up the callers a little. The helper is not intended for new code, everything without the interface set in stone should use vfs_permission() Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-09[PATCH] add a vfs_permission helperChristoph Hellwig5-14/+29
Most permission() calls have a struct nameidata * available. This helper takes that as an argument and thus makes sure we pass it down for lookup intents and prepares for per-mount read-only support where we need a struct vfsmount for checking whether a file is writeable.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering15-20/+1
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-08[PATCH] fix de_thread() vs send_group_sigqueue() raceOleg Nesterov1-3/+7
When non-leader thread does exec, de_thread calls release_task(leader) before calling exit_itimers(). If local timer interrupt happens in between, it can oops in send_group_sigqueue() while taking ->sighand->siglock == NULL. However, we can't change send_group_sigqueue() to check p->signal != NULL, because sys_timer_create() does get_task_struct() only in SIGEV_THREAD_ID case. So it is possible that this task_struct was already freed and we can't trust p->signal. This patch changes de_thread() so that leader released after exit_itimers() call.

2005-11-07[PATCH] unbindable mountsRam Pai3-26/+65
An unbindable mount does not forward or receive propagation. Also unbindable mount disallows bind mounts. The semantics is as follows. Bind semantics: It is invalid to bind mount an unbindable mount. Move semantics: It is invalid to move an unbindable mount under shared mount. Clone-namespace semantics: If a mount is unbindable in the parent namespace, the corresponding cloned mount in the child namespace becomes unbindable too. Note: there is subtle difference, unbindable mounts cannot be bind mounted but can be cloned during clone-namespace.
