vfs_{create,mkdir,mknod} each begin with a call to may_create(), which returns EEXIST if the object already exists. This check is therefore unnecessary. (In the NFSv2 case, nfsd_proc_create also has such a check. Contrary to RFC 1094, our code seems to believe that a CREATE of an existing file should succeed. I'm leaving that behavior alone.)

There's some odd logic in nfsd_create() that allows it to be called with the parent directory either locked or unlocked. The only already-locked caller is NFSv2's nfsd_proc_create(). It's less confusing to split out the unlocked case into a separate function which the NFSv2 code can call directly. Also fix some comments while we're here. Signed-off-by: NJ.

Create and other nfsd ops generally assume we can call lookup_one_len on inodes with S_IFDIR set.

lookup_one_len already has this check. The only effect of this patch is to return access instead of perm in the 0-length-filename case. I actually prefer nfserr_perm (or _inval?), but I doubt anyone cares. The isdotent check seems redundant too, but I worry that some client might actually care about that strange nfserr_exist error.

由 Oleg Drokin 提交于
When doing a create (mkdir/mknod) on a name, it's worth checking the name exists first before returning EACCES in case the directory is not writeable by the user. This makes return values on the client more consistent regardless of whenever the entry there is cached in the local cache or not. Another positive side effect is certain programs only expect EEXIST in that case even despite POSIX allowing any valid error to be returned.

The current jump_label.h includes bug.h for things such as WARN_ON(). This makes the header problematic for inclusion by kernel.h or any headers that kernel.h includes, since bug.h includes kernel.h (circular dependency). The inclusion of atomic.h is similarly problematic. Thus, this should make jump_label.h 'includable' from most places.

The addition of jump label support in dynamic_debug caused an unexpected warning in exactly one file in the kernel: drivers/media/dvb-frontends/cxd2841er.c: In function 'cxd2841er_tune_tc': include/linux/dynamic_debug.h:134:3: error: 'carrier_offset' may be used uninitialized in this function [-Werror=maybe-uninitialized] __dynamic_dev_dbg(&descriptor, dev, fmt, \ ^~~~~~~~~~~~~~~~~ drivers/media/dvb-frontends/cxd2841er.c:3177:11: note: 'carrier_offset' was declared here int ret, carrier_offset; ^~~~~~~~~~~~~~ The problem seems to be that the compiler gets confused by the extra conditionals in static_branch_unlikely, to the point where it can no longer keep track of which branches have already been taken, and it doesn't realize that this variable is now always initialized when it gets used. I have done lots of randconfig kernel builds and could not find any other file with this behavior, so I assume it's a rare enough glitch that we don't need to change the jump label support but instead just work around the warning in the driver. To achieve that, I'm moving the check for the return value into the switch() statement, which is an obvious transformation, but is enough to un-confuse the compiler here. The resulting code is not as nice to read, but at least we retain the behavior of warning if it gets changed to actually access an uninitialized carrier offset value in the future.

The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value. Semantic patches for this change (at least most of them): virtual patch virtual context @r@ identifier f, attrs; @@ f(..., - struct dma_attrs *attrs + unsigned long attrs , ...) { ... } @@ identifier r.f; @@ f(..., - NULL + 0 ) and // Options: --all-includes virtual patch virtual context @r@ identifier f, attrs; type t; @@ t f(..., struct dma_attrs *attrs); @@ identifier r.f; @@ f(..., - NULL + 0 ) Link: http://lkml.kernel.org/r/1468399300-5399-2-git-send-email-k.kozlowski@samsung.comSigned-off-by: NKrzysztof Kozlowski <k.kozlowski@samsung.com> Acked-by: NVineet Gupta <vgupta@synopsys.com> Acked-by: NRobin Murphy <robin.murphy@arm.com> Acked-by: NHans-Christian Noren Egtvedt <egtvedt@samfundet.no> Acked-by: Mark Salter <msalter@redhat.com> [c6x] Acked-by: Jesper Nilsson <jesper.nilsson@axis.com> [cris] Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> [drm] Reviewed-by: NBart Van Assche <bart.vanassche@sandisk.com> Acked-by: Joerg Roedel <jroedel@suse.de> [iommu] Acked-by: Fabien Dessenne <fabien.dessenne@st.com> [bdisp] Reviewed-by: Marek Szyprowski <m.szyprowski@samsung.com> [vb2-core] Acked-by: David Vrabel <david.vrabel@citrix.com> [xen] Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> [xen swiotlb] Acked-by: Joerg Roedel <jroedel@suse.de> [iommu] Acked-by: Richard Kuo <rkuo@codeaurora.org> [hexagon] Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> [m68k] Acked-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> [s390] Acked-by: NBjorn Andersson <bjorn.andersson@linaro.org> Acked-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no> [avr32] Acked-by: Vineet Gupta <vgupta@synopsys.com> [arc] Acked-by: Robin Murphy <robin.murphy@arm.com> [arm64 and dma-iommu] Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

While not an issue now, eventually we will have independent users of the extable.h file and we will stop sourcing it via module.h header. In testing that pending work, with very sparse builds, characteristic of an "allnoconfig" on various architectures, we can sometimes hit an instance where the very basic standard definitions aren't present, resulting in: include/linux/extable.h:26:9: error: 'NULL' undeclared (first use in this function) To be clear, this isn't a regression, since currently extable.h is only used by module.h -- however, we will need this addition present before we start migrating exception table users off module.h and onto extable.h during the next release cycle.
