This replaces all references of NILFS_I_NILFS(inode)->ns_bdev with inode->i_sb->s_bdev and unfolds remaining uses of NILFS_I_NILFS inline function. Before 2.6.37, referring to a nilfs object from inodes needed a conditional judgement, and NILFS_I_NILFS was helpful to simplify it. But now we can simply do it by going through a super block instance like inode->i_sb->s_fs_info. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

When shrinking the filesystem, segments to be truncated must be test if they are busy or not, and unneeded sufile block should be deleted. This adds routines for the truncation. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This adds a new ioctl command which limits range of segment to be allocated. This is intended to gather data whithin a range of the partition before shrinking the filesystem, or to control new log location for some purpose. If a range is specified by the ioctl, segment allocator of nilfs tries to allocate new segments from the range unless no free segments are available there.

The super root block is newly-allocated each time it is written back to disk, so unused portion of the block should be cleared. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

The size of super root structure depends on inode size, so NILFS_SR_BYTES macro should be a function of the inode size. This fixes the issue. Even though a different size value will be written for a possible future filesystem with extended inode, but fortunately this does not break disk format compatibility.

Previously, nilfs was cloning pages for mmapped region to freeze their data and ensure consistency of checksum during writeback cycles. A private page allocator was used for this page cloning. But, we no longer need to do that since clear_page_dirty_for_io function sets up pte so that vm_ops->page_mkwrite function is called right before the mmapped pages are modified and nilfs_page_mkwrite function can safely wait for the pages to be written back to disk. So, this stops making a copy of mmapped pages during writeback, and eliminates the private page allocation and deallocation functions from nilfs.

After having applied commit 9954e7af ("nilfs2: add free entries count only if clear bit operation succeeded"), a free routine of nilfs came to fall into an infinite loop, outputting the same message endlessly: nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed ... That patch broke the routine so that a loop counter is never updated in an abnormal state. This fixes the regression. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Commit a626ca6a ("vm: fix vm_pgoff wrap in stack expansion") fixed the case of an expanding mapping causing vm_pgoff wrapping when you had downward stack expansion. But there was another case where IA64 and PA-RISC expand mappings: upward expansion. This fixes that case too.

Linux kernel excludes guard page when performing mlock on a VMA with down-growing stack. However, some architectures have up-growing stack and locking the guard page should be excluded in this case too. This patch fixes lvm2 on PA-RISC (and possibly other architectures with up-growing stack). lvm2 calculates number of used pages when locking and when unlocking and reports an internal error if the numbers mismatch. [ Patch changed fairly extensively to also fix /proc/<pid>/maps for the grows-up case, and to move things around a bit to clean it all up and share the infrstructure with the /proc bits. Tested on ia64 that has both grow-up and grow-down segments - Linus ] Signed-off-by: NMikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> Tested-by: NTony Luck <tony.luck@gmail.com> Cc: stable@kernel.org Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

If we're using vga switcheroo, the device may be turned off and poking it can return random state. This provokes an OOPS fixed separately by 8ff887c847 (drm/i915/dp: Be paranoid in case we disable a DP before it is attached). Trying to use and respond to events on a device that has been turned off by the user is in principle a silly thing to do.

Despite the fixes in 548f245b (drm/i915: fix per-pipe reads after "cleanup"), we missed one neighbouring read that was mistakenly replaced with the reg value in 9db4a9c7 (drm/i915: cleanup per-pipe reg usage). This was preventing us from correctly determining the mode the BIOS left the panel in for machines that neither have an OpRegion nor access to the VBT, (e.g. the EeePC 700).
