- introduce ktime_t: nanosecond-resolution time format. - eliminate the plain s64 scalar type, and always use the union. This simplifies the arithmetics. Idea from Roman Zippel. Signed-off-by:

Turn noatime and nodiratime into per-mount instead of per-sb flags. After all the preparations this is a rather trivial patch. The mount code needs to treat the two options as per-mount instead of per-superblock, and touch_atime needs to be changed to check the new MNT_ flags in addition to the MS_ flags that are kept for filesystems that are always noatime/nodiratime but not user settable anymore. Besides that core code only nfs needed an update because it's leaving atime updates to the server and thus sets the S_NOATIME flag on every inode, but needs to know whether it's a real noatime mount for an getattr optimization. While we're at it I've killed the IS_NOATIME/IS_NODIRATIME macros that were only used by touch_atime. Signed-off-by:

Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.

Add a compat_ioctl method to the dasd driver so the last entries in arch/s390/kernel/compat_ioctl.c can go away. Unlike the previous attempt this one does not replace the ioctl method with an unlocked_ioctl method so that the ioctl_by_bdev calls in s390 partition code continue to work. Signed-off-by:

This patch implements generic handling of RTC_IRQP_READ32, RTC_IRQP_SET32, RTC_EPOCH_READ32 and RTC_EPOCH_SET32 in fs/compat_ioctl.c. It's based on the x86_64 code which needed a little massaging to be endian-clean. parisc used COMPAT_IOCTL or generic w_long handlers for these whichce is wrong and can't work because the ioctls encode sizeof(unsigned long) in their ioctl number. parisc also duplicated COMPAT_IOCTL entries for other rtc ioctls which I remove in this patch, too.

The comment in compat.c is wrong, every architecture provides a get_compat_sigevent() for the IPC compat code already. This basically moves the x86_64 version to common code and removes all the others. Signed-off-by:

These ioctls are definitely not compat clean, but we already have a proper handler in common code, over-riding it in architecture code is counter-productive. Signed-off-by:

All callers use touch_atime now which takes a vfsmount and allows us to implement per-mount noatime. Signed-off-by:

Christoph Hellwig authored
After my lookup_hash patch ->d_revalidate always gets a valid struct nameidata passed (unless you use lookup_one_len which autofs4 doesn't), so we can switch it from update_atime to touch_atime. This is a bit of an academic excercise because autofs has a 1:1 vfsmount superblock relation, but I want to get rid of update_atime so filesystems authors can't easily screw up per-mountpoint noatime support.

To allow various options to work per-mount instead of per-sb we need a struct vfsmount when updating ctime and mtime. This preparation patch replaces the inode_update_time routine with a file_update_atime routine so we can easily get at the vfsmount. (and the file makes more sense in this context anyway). Also get rid of the unused second argument - we always want to update the ctime when calling this routine. Signed-off-by:

) From: Christoph Hellwig <hch@lst.de> The xattr code has rather complex permission checks because the rules are very different for different attribute namespaces. This patch moves as much as we can into the generic code. Currently all the major disk based filesystems duplicate these checks, while many minor filesystems or network filesystems lack some or all of them. To do this we need defines for the extended attribute names in common code, I moved them up from JFS which had the nicest defintions. Signed-off-by:

I have heard some complaints about people not finding CONFIG_CRASH_DUMP option and also some objections about its dependency on CONFIG_EMBEDDED. The following patch ends that dependency. I thought of hiding it under CONFIG_KEXEC, but CONFIG_PHYSICAL_START could also be used for some reasons other than kexec/kdump and hence left it visible. I will also update the documentation accordingly. o Following patch removes the config dependency of CONFIG_PHYSICAL_START on CONFIG_EMBEDDED. The reason being CONFIG_CRASH_DUMP option for kdump needs CONFIG_PHYSICAL_START which makes CONFIG_CRASH_DUMP depend on CONFIG_EMBEDDED. It is not always obvious for kdump users to choose CONFIG_EMBEDDED. o It also shifts the palce where this option appears, to make it closer to kexec and kdump options. Signed-off-by:
