When a system runs out of memory and the function ptlrpc_register_bulk() is called from ptl_send_rpc() the call to LNetMEAttach() fails due to failure to allocate memory. This forces the code into an error path, which most probably previously went untested. The error path: if (rc != 0) { CERROR("%s: LNetMEAttach failed x"LPU64"/%d: rc = %dn", desc->bd_export->exp_obd->obd_name, xid, posted_md, rc); break; } This print assumes that desc->bd_export is not NULL. However, it is. In fact it is expected to be NULL. desc->bd_import is the correct structure to access in this case.

John L. Hammond authored
ll_lookup_it() checks for O_CREAT in struct lookup_intent's it_create_mode member which is nonsensical, as it_create_mode is used for file mode bits (S_IFREG, S_IRUSR, ...). Fix this by just checking for IT_CREATE in it_op. This will not affect the behavior of either function, since if O_CREATE (0100) is actually set in o_create_mode then IT_CREATE must have been set in it_op. In ll_atomic_open() check for O_CREAT in the open_flags parameter rather than testing mode.

Pull workqueue fixes from Tejun Heo: "This contains one important fix. The NUMA support added a while back broke ordering guarantees on ordered workqueues. It was enforced by having single frontend interface with @max_active == 1 but the NUMA support puts multiple interfaces on unbound workqueues on NUMA machines thus breaking the ordered guarantee. This is fixed by disabling NUMA support on ordered workqueues.

Pull vfs dentry reference count fix from Al Viro. This fixes a possible inode_permission NULL pointer dereference (and other problems) that were due to the root dentry count being decremented too much. In commit 48a066e7 ("RCU'd vfsmounts") the placement of clearing the LOOKUP_RCU bit changed, and we then returned failure of incrementing the lockref on the parent dentry with LOOKUP_RCU cleared. But that meant we needed to go through the same cleanup routines that the later failures did wrt LOOKUP_ROOT and nd->root. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fix bogus path_put() of nd->root after some unlazy_walk() failures

Catalin Marinas authored
PTE_PROT_NONE means that a pte is present but does not have any read/write attributes. However, setting the memory type like pgprot_writecombine() is allowed and such bits overlap with PTE_PROT_NONE. This causes mmap/munmap issues in drivers that change the vma->vm_pg_prot on PROT_NONE mappings. This patch reverts the PTE_FILE/PTE_PROT_NONE shift in commit 59911ca4 (ARM64: mm: Move PTE_PROT_NONE bit) and moves PTE_PROT_NONE together with the other software bits. Signed-off-by:

Failure to grab reference to parent dentry should go through the same cleanup as nd->seq mismatch. As it is, we might end up with caller thinking it needs to path_put() nd->root, with obvious nasty results once we'd hit that bug enough times to drive the refcount of root dentry all the way to zero...
