2016-10-16staging: lustre: clio: Revise read ahead implementationJinshan Xiong
In this implementation, read ahead will hold the underlying DLM lock to add read ahead pages. A new cl_io operation cio_read_ahead() is added for this purpose. It takes parameter cl_read_ahead{} so that each layer can adjust it by their own requirements. For example, at OSC layer, it will make sure the read ahead region is covered by a LDLM lock; at the LOV layer, it will make sure that the region won't cross stripe boundary. Legacy callback cpo_is_under_lock() is removed.

2016-10-16staging: lustre: obdclass: Add synchro in lu_context_key_degister()Patrick Valentin
When unloading a module, it may happen that lu_context_key_degister() removes a key while a thread is either registering it in a new context (lu_context_init(), lu_context_refill()), or using it when exiting from a context (lu_context__exit(), lu_context__fini()). In these cases, we reference a key which no longer exists, and the system crashes either because we use a *POISON'ed* pointer in key_fini() -> key->lct_fini(), or because one of the following assertions fails: - lu_context_key_degister(): ASSERTION(cfs_atomic_read(&key->lct_used) == 1) failed: key has instances: 2 - lu_context_exit(): ASSERTION(key != NULL) - key_fini(): ASSERTION(atomic_read(&key->lct_used) > 1) This can also leads to SLAB objects which are not freed: slab error in kmem_cache_destroy(): cache `echo_thread_kmem': Can't free all objects Note: ptlrpc service threads need to call lu_context_init/fini in each loop (for each RPC), and this could be a big performance issue on fat SMP machines if we add serialization by a spinlock and need to lock/unlock it for multiple times for each RPC. So the aim of this patch, which only impacts some low frequently used functions, is: 1) to add a synchronization in lu_context_key_quiesce(), also called by lu_context_key_degister(), to wait until all key::lct_init() methods have completed, by serializing with keys_fill() 2) to add a synchronization in lu_context_key_degister(), to wait until all transient contexts referencing this key have run key::lct_fini() method Signed-off-by: Patrick Valentin <patrick.valentin@bull.net> Signed-off-by: Gregoire Pichon <gregoire.pichon@bull.net> Intel-bug-id: https://jira.hpdd.intel.com/browse/LU-6049 Reviewed-on: http://review.whamcloud.com/13164 Reviewed-by: Fan Yong <fan.yong@intel.com> Reviewed-by: Alex Zhuravlev <alexey.zhuravlev@intel.com> Reviewed-by: Oleg Drokin <oleg.drokin@intel.com> Signed-off-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-10-16objtool: Skip all "unreachable instruction" warnings for gcov kernelsJosh Poimboeuf
Recently objtool has started reporting a few "unreachable instruction" warnings when CONFIG_GCOV is enabled for newer versions of GCC. Usually this warning means there's some new control flow that objtool doesn't understand. But in this case, objtool is correct and the instructions really are inaccessible. It's an annoying quirk of gcov, but it's harmless, so it's ok to just silence the warnings. With older versions of GCC, it was relatively easy to detect gcov-specific instructions and to skip any unreachable warnings produced by them. But GCC 6 has gotten craftier. Instead of continuing to play whack-a-mole with gcov, just use a bigger, more permanent hammer and disable unreachable warnings for the whole file when gcov is enabled. This is fine to do because a) unreachable warnings are usually of questionable value; and b) gcov isn't used for production kernels and we can relax the checks a bit there.

2016-10-16objtool: Improve rare switch jump table pattern detectionJosh Poimboeuf
GCC 6 added a new switch statement jump table optimization which makes objtool's life harder. It looks like: mov [rodata addr],%reg1 ... some instructions ... jmpq *(%reg1,%reg2,8) The optimization is quite rare, but objtool still needs to be able to identify the pattern so that it can follow all possible control flow paths related to the switch statement. In order to detect the pattern, objtool starts from the indirect jump and scans backwards through the function until it finds the first instruction in the pattern. If it encounters an unconditional jump along the way, it stops and considers the pattern to be not found. As it turns out, unconditional jumps can happen, as long as they are small forward jumps within the range being scanned. This fixes the following warnings: drivers/infiniband/sw/rxe/rxe_comp.o: warning: objtool: rxe_completer()+0x2f4: sibling call from callable instruction with changed frame pointer drivers/infiniband/sw/rxe/rxe_resp.o: warning: objtool: rxe_responder()+0x10f: sibling call from callable instruction with changed frame pointer Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com> Cc: Andy Lutomirski <luto@kernel.org> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.

2016-10-16arm64: dts: rockchip: remove always-on and boot-on from vcc_sdShawn Lin
Please don't add these for vcc_sd, and mmc-core/driver will control it. Otherwise, it will waste energy even without sdmmc in slot. Moreover, it will causes a bug: If we insert/remove sd card, we could see [9.337271] mmc0: new ultra high speed SDR25 SDHC card at address 0007 [9.345144] mmcblk0: mmc0:0007 SD32G 29.3 GiB This is okay for normal sd insert/remove test, but when I debug some issues for sdmmc, I did unbind/bind test. And there is a interesting phenomenon when we bind the driver again: [58.314069] mmc0: new high speed SDHC card at address 0007 [58.320282] mmcblk0: mmc0:0007 SD32G 29.3 GiB So the sd card could just support high speed without power cycle since the vcc_sd is always on, which makes the sd card fail to reinit its internal ocr mask.

2016-10-14fs/super.c: fix race between freeze_super() and thaw_super()Oleg Nesterov
Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering. In this case thaw_super() will wrongly call s_op->unfreeze_fs() before it was actually frozen, and call sb_freeze_unlock() which leads to the unbalanced percpu_up_write(). Unfortunately lockdep can't detect this, so this triggers misc BUG_ON()'s in kernel/rcu/sync.c.

2016-10-14overlayfs: Fix setting IOP_XATTR flagVivek Goyal
ovl_fill_super calls ovl_new_inode to create a root inode for the new superblock before initializing sb->s_xattr. This wrongly causes IOP_XATTR to be cleared in i_opflags of the new inode, causing SELinux to log the following message: SELinux: (dev overlay, type overlay) has no xattr support Fix this by initializing sb->s_xattr and similar fields before calling ovl_new_inode.

2016-10-14iov_iter: kernel-doc import_iovec() and rw_copy_check_uvector()Vegard Nossum
Both import_iovec() and rw_copy_check_uvector() take an array (typically small and on-stack) which is used to hold an iovec array copy from userspace. This is to avoid an expensive memory allocation in the fast path (i.e. few iovec elements). The caller may have to check whether these functions actually used the provided buffer or allocated a new one -- but this differs between the too. Let's just add a kernel doc to clarify what the semantics are for each function. Signed-off-by: Vegard Nossum <vegard.nossum@oracle.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
