GFS2: merge window
Here is a list of patches we've accumulated for GFS2 for the current upstream
merge window. Last window's set was short, but I warned that this one would
be bigger, and so it is. We've got 19 patches:
- A patch from Abhi Das to propagate the GFS2_DIF_SYSTEM bit so that newly
added journals don't get flagged, deleted, and recreated by fsck.gfs2.
- Two patches from Andreas Gruenbacher to improve GFS2 performance where
extended attributes are involved.
- A patch from Andy Price to fix a suspicious rcu dereference error.
- Two patches from Ben Marzinski that rework how GFS2's NFS cookies are
managed. This fixes readdir problems with nfs-over-gfs2.
- A patch from Ben Marzinski that fixes a race in unmounting GFS2.
- A set of four patches from me to move the resource group reservations
inside the gfs2 inode to improve performance and fix a bug whereby
get_write_access improperly prevented some operations like chown.
- A patch from me to spinlock-protect the setting of system statfs file data.
This was causing small discrepancies between df and du.
- A patch from me to reintroduce a timeout while clearing glocks which was
accidentally dropped some time ago.
- A patch from me to wait for iopen glock dequeues in order to improve
deleting of files that were unlinked from a different cluster node.
- A patch from me to ensure metadata address spaces get truncated when an
inode is evicted.
- A patch from me to fix a bug in which a memory leak could occur in some
error cases when inodes were trying to be created.
- A patch to consistently use iopen glocks to transition from the unlinked
state to the deleted state.
- A patch to fix a glock reference count error when inode creation fails.
- A patch from Junxiao Bi to fix an flock panic.
- A patch from Markus Elfring that removes an unnecessary if.

Merge branch 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull misc vfs updates from Al Viro: "All kinds of stuff. That probably should've been 5 or 6 separate branches, but by the time I'd realized how large and mixed that bag had become it had been too close to -final to play with rebasing. Some fs/namei.c cleanups there, memdup_user_nul() introduction and switching open-coded instances, burying long-dead code, whack-a-mole of various kinds, several new helpers for ->llseek(), assorted cleanups and fixes from various people, etc. One piece probably deserves special mention - Neil's lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets called without ->i_mutex and tries to avoid ever taking it. That, of course, means that it's not useful for any directory modifications, but things like getting inode attributes in nfds readdirplus are fine with that. I really should've asked for moratorium on lookup-related changes this cycle, but since I hadn't done that early enough... I *am* asking for that for the coming cycle, though - I'm going to try and get conversion of i_mutex to rwsem with ->lookup() done under lock taken shared. There will be a patch closer to the end of the window, along the lines of the one Linus had posted last May - mechanical conversion of ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/ inode_is_locked()/inode_lock_nested(). To quote Linus back then: ----- | This is an automated patch using | | sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/' | sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/' | sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[ ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/' | sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/' | sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/' | | with a very few manual fixups ----- I'm going to send that once the ->i_mutex-affecting stuff in -next gets mostly merged (or when Linus says he's about to stop taking merges)" * 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (63 commits) nfsd: don't hold i_mutex over userspace upcalls fs:affs:Replace time_t with time64_t fs/9p: use fscache mutex rather than spinlock proc: add a reschedule point in proc_readfd_common() logfs: constify logfs_block_ops structures fcntl: allow to set O_DIRECT flag on pipe fs: __generic_file_splice_read retry lookup on AOP_TRUNCATED_PAGE fs: xattr: Use kvfree() [s390] page_to_phys() always returns a multiple of PAGE_SIZE nbd: use ->compat_ioctl() fs: use block_device name vsprintf helper lib/vsprintf: add %*pg format specifier fs: use gendisk->disk_name where possible poll: plug an unused argument to do_poll amdkfd: don't open-code memdup_user() cdrom: don't open-code memdup_user() rsxx: don't open-code memdup_user() mtip32xx: don't open-code memdup_user() [um] mconsole: don't open-code memdup_user_nul() [um] hostaudio: don't open-code memdup_user() ... |

Last time I checked during the 4.4-rc cycle, there were no users of the old interfaces, as has been the case for some time now. Breakage due to conflicting development is possible, in which case this pull will have to be reverted - however, these changes have been in linux-next since Dec 7th without any problems reported. Removal of that then allows us to change the way we track components internally, allowing us to release data that has been used for matching at the appropriate time, thereby allowing any resource leaks caused by that missing functionality to be resolved" * 'component' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: component: add support for releasing match data component: track components via array rather than list component: move check for unbound master into try_to_bring_up_masters() component: remove old add_components method |

kvm: x86: Fix vmwrite to SECONDARY_VM_EXEC_CONTROL
vmx_cpuid_tries to update SECONDARY_VM_EXEC_CONTROL in the VMCS, but
it will cause a vmwrite error on older CPUs because the code does not
check for the presence of CPU_BASED_ACTIVATE_SECONDARY_CONTROLS.
This will get rid of the following trace on e.g. Core2 6600:
vmwrite error: reg 401e value 10 (err 12)

regmap: Changes for v4.5
There's no real overall theme to the regmap changes for this release, it's a collection of individual features. The main bits are: - Support for 64 bit registers, mainly for MMIO use, from Xiubo Li. - Support for trigger type configuration for regmap-irq from Laxman Dewangan. - Use native physical I/O for MMIO register maps to avoid confusion with the conversions that readl() and writel() do to little endian on big endian systems (with some DT updates to fix some workarounds people were doing), code from Simon Arlott. - Use a binary search rather than iteraton to improve the runtime performance of the rbtree code from Nikesh Oswal. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJWk9fCAAoJECTWi3JdVIfQpn4H/0nJwe03NcY829ioXEP+ICHF yE1Y8FH5q+NeVAo+bbQQYiTEGRQbp+E82S7OTfNKY0Z3QkPRZVtz5yMI/L2yK8I0 HT2WJakJY6LhQfJcWgjRRfBrQvH/+2fk+3mAs0q0r+mrOoitfCb1V7uaNoVF+Hyk 0mli7lcf2MB1akF98SwcaM3v3HhGXUUxFnclvzsMWTEp4GCt/xqwEkTm/0xn0N17 rlxLe1RtaGMM0xfbEN3sfDX5YAPmtBi4m+CdrP6l5qgisnABPIq83RKRFNyQBcGD 8OkA2Iu0B7eJPFPQ8sD/hELBNYyrVTwvhJQdJnle7++/Dis9EMiffMRSW8eZh+0= =JaJb -----END PGP SIGNATURE----- Merge tag 'regmap-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "There's no real overall theme to the regmap changes for this release, it's a collection of individual features.

Workqueue now has a stall detector which dumps workqueue state if any worker pool hasn't made forward progress over a certain amount of time (30s by default) and also triggers a warning if a workqueue which can be used in memory reclaim path tries to wait on something which can't be.

One thing I should note is that these pieces of documentation are fairly large files: .../RCU/Design/Requirements/Requirements.html | 2897 ++++++++++++++++++++ .../RCU/Design/Requirements/Requirements.htmlx | 2741 ++++++++++++++++++ and are written in HTML, not the usual .txt style.
