vfs: add RENAME_WHITEOUT

2014-10-23T22:14:37Z

This adds a new RENAME_WHITEOUT flag. This flag makes rename() create a whiteout of source. The whiteout creation is atomic relative to the rename. Signed-off-by: Miklos Szeredi

Pull SCSI target updates from Nicholas Bellinger: "Here are the target updates for v3.18-rc2 code. These where originally destined for -rc1, but due to the combination of travel last week for KVM Forum and my mistake of taking the three week merge window literally, the pull request slipped.. Apologies for that. Things where reasonably quiet this round. The highlights include: - New userspace backend driver (target_core_user.ko) by Shaohua Li and Andy Grover - A number of cleanups in target, iscsi-taret and qla_target code from Joern Engel - Fix an OOPs related to queue full handling with CHECK_CONDITION status from Quinn Tran - Fix to disable TX completion interrupt coalescing in iser-target, that was causing problems on some hardware - Fix for PR APTPL metadata handling with demo-mode ACLs I'm most excited about the new backend driver that uses UIO + shared memory ring to dispatch I/O and control commands into user-space. This was probably the most requested feature by users over the last couple of years, and opens up a new area of development + porting of existing user-space storage applications to LIO. Thanks to Shaohua + Andy for making this happen. Also another honorable mention, a new Xen PV SCSI driver was merged via the xen/tip.git tree recently, which puts us now at 10 target drivers in upstream! Thanks to David Vrabel + Juergen Gross for their work to get this code merged" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (40 commits) target/file: fix inclusive vfs_fsync_range() end iser-target: Disable TX completion interrupt coalescing target: Add force_pr_aptpl device attribute target: Fix APTPL metadata handling for dynamic MappedLUNs qla_target: don't delete changed nacls target/user: Recalculate pad size inside is_ring_space_avail() tcm_loop: Fixup tag handling iser-target: Fix smatch warning target/user: Fix up smatch warnings in tcmu_netlink_event target: Add a user-passthrough backstore target: Add documentation on the target userspace pass-through driver uio: Export definition of struct uio_device target: Remove unneeded check in sbc_parse_cdb target: Fix queue full status NULL pointer for SCF_TRANSPORT_TASK_SENSE qla_target: rearrange struct qla_tgt_prm qla_target: improve qlt_unmap_sg() qla_target: make some global functions static qla_target: remove unused parameter target: simplify core_tmr_abort_task target: encapsulate smp_mb__after_atomic() ...

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static. Really minor stuff" * git://git.infradead.org/users/eparis/audit: (31 commits) audit: rename audit_log_remove_rule to disambiguate for trees audit: cull redundancy in audit_rule_change audit: WARN if audit_rule_change called illegally audit: put rule existence check in canonical order next: openrisc: Fix build audit: get comm using lock to avoid race in string printing audit: remove open_arg() function that is never used audit: correct AUDIT_GET_FEATURE return message type audit: set nlmsg_len for multicast messages. audit: use union for audit_field values since they are mutually exclusive audit: invalid op= values for rules audit: use atomic_t to simplify audit_serial() kernel/audit.c: use ARRAY_SIZE instead of sizeof/sizeof[0] audit: reduce scope of audit_log_fcaps audit: reduce scope of audit_net_id audit: arm64: Remove the audit arch argument to audit_syscall_entry arm64: audit: Add audit hook in syscall_trace_enter/exit() audit: x86: drop arch from __audit_syscall_entry() interface sparc: implement is_32bit_task sparc: properly conditionalize use of TIF_32BIT ...

Pull s390 updates from Martin Schwidefsky: "This patch set contains the main portion of the changes for 3.18 in regard to the s390 architecture. It is a bit bigger than usual, mainly because of a new driver and the vector extension patches. The interesting bits are: - Quite a bit of work on the tracing front. Uprobes is enabled and the ftrace code is reworked to get some of the lost performance back if CONFIG_FTRACE is enabled. - To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the IPTE range facility is added. - The rwlock code is re-factored to improve writer fairness and to be able to use the interlocked-access instructions. - The kernel part for the support of the vector extension is added. - The device driver to access the CD/DVD on the HMC is added, this will hopefully come in handy to improve the installation process. - Add support for control-unit initiated reconfiguration. - The crypto device driver is enhanced to enable the additional AP domains and to allow the new crypto hardware to be used. - Bug fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (39 commits) s390/ftrace: simplify enabling/disabling of ftrace_graph_caller s390/ftrace: remove 31 bit ftrace support s390/kdump: add support for vector extension s390/disassembler: add vector instructions s390: add support for vector extension s390/zcrypt: Toleration of new crypto hardware s390/idle: consolidate idle functions and definitions s390/nohz: use a per-cpu flag for arch_needs_cpu s390/vtime: do not reset idle data on CPU hotplug s390/dasd: add support for control unit initiated reconfiguration s390/dasd: fix infinite loop during format s390/mm: make use of ipte range facility s390/setup: correct 4-level kernel page table detection s390/topology: call set_sched_topology early s390/uprobes: architecture backend for uprobes s390/uprobes: common library for kprobes and uprobes s390/rwlock: use the interlocked-access facility 1 instructions s390/rwlock: improve writer fairness s390/rwlock: remove interrupt-enabling rwlock variant. s390/mm: remove change bit override support ...
