2015-10-17ver_linux: module-init-tools, look for numerical input, not field numberAlexander Kapshuk
Rely on regex to find the version number, rather than rely on numerical input to be found in a particular input field. Tested on: Gentoo Linux Debian 6.0.10 Oracle Linux Server release 7.1 Signed-off-by: Alexander Kapshuk <alexander.kapshuk@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-10-17ver_linux: util-linux, 'fdformat' not ubiquitous any longerAlexander Kapshuk
The current implementation relies on 'fdformat' to output the version of 'util-linux'. This does not seem to be reliable any longer, as 'fdformat' does not seem to come preinstalled in all ditros these days. The proposed implementation uses 'mount' to output both the version of 'util-linux' and 'mount' proper, as 'mount' is also a part of the 'util-linux' package. Tested on: Gentoo Linux Debian 6.0.10 Oracle Linux Server release 7.1 Rely on regex to find the version number, rather than a field number.

2015-10-17misc: sram: extend usage of reserved partitionsVladimir Zapolskiy
This change adds functionality to operate on reserved SRAM partitions described in device tree file. Two partition properties are added, "pool" and "export", the first one allows to share a specific partition for usage by a kernel consumer in the same manner as it is done for the whole SRAM device, and "export" property provides access to some SRAM area from userspace over sysfs interface. Practically it is possible to specify both properties for an SRAM partition, however simultaneous access from a kernel consumer and from userspace is not serialized, but still the combination may be useful for debugging purpose. The change opens the following scenarios of SRAM usage: * updates in a particular SRAM area specified by offset and size are done by bootloader, then this information is utilized by the kernel, * a particular SRAM area is rw accessed from userspace, the stored data is persistent on soft reboots, * a device driver secures SRAM area for its purposes, * etc. Note, strictly speaking the added optional properties describe policy of SRAM usage, rather than hardware, but here the policy mostly resembles flash partitions in devicetree, which is undoubtedly a very popular option but it does not describe hardware.

This patch modifies the id and name of external connector with the additional prefix to clarify both attribute and meaning of external connector as following: - EXTCON_CHG_* mean the charger connector. - EXTCON_JACK_* mean the jack connector. - EXTCON_DISP_* mean the display port connector. Following table show the new name of external connector with old name: -------------------------------------------------- Old extcon name | New extcon name | -------------------------------------------------- EXTCON_TA | EXTCON_CHG_USB_DCP | EXTCON_CHARGE_DOWNSTREAM| EXTCON_CHG_USB_CDP | EXTCON_FAST_CHARGER | EXTCON_CHG_USB_FAST | EXTCON_SLOW_CHARGER | EXTCON_CHG_USB_SLOW | -------------------------------------------------- EXTCON_MICROPHONE | EXTCON_JACK_MICROPHONE | EXTCON_HEADPHONE | EXTCON_JACK_HEADPHONE | EXTCON_LINE_IN | EXTCON_JACK_LINE_IN | EXTCON_LINE_OUT | EXTCON_JACK_LINE_OUT | EXTCON_VIDEO_IN | EXTCON_JACK_VIDEO_IN | EXTCON_VIDEO_OUT | EXTCON_JACK_VIDEO_OUT | EXTCON_SPDIF_IN | EXTCON_JACK_SPDIF_IN | EXTCON_SPDIF_OUT | EXTCON_JACK_SPDIF_OUT | -------------------------------------------------- EXTCON_HMDI | EXTCON_DISP_HDMI | EXTCON_MHL | EXTCON_DISP_MHL | EXTCON_DVI | EXTCON_DISP_DVI | EXTCON_VGA | EXTCON_DISP_VGA | -------------------------------------------------- And, when altering the name of USB charger connector, EXTCON refers to the "Battery Charging v1.2 Spec and Adopters Agreement"[1] to use the standard name of USB charging port as following.

2015-10-10namei: results of d_is_negative() should be checked after dentry revalidationTrond Myklebust
Leandro Awa writes: "After switching to version 4.1.6, our parallelized and distributed workflows now fail consistently with errors of the form: T34: ./regex.c:39:22: error: config.h: No such file or directory From our 'git bisect' testing, the following commit appears to be the possible cause of the behavior we've been seeing: commit 766c4cbfacd8" Al Viro says: "What happens is that 766c4cbfacd8 got the things subtly wrong. We used to treat d_is_negative() after lookup_fast() as "fall with ENOENT". That was wrong - checking ->d_flags outside of ->d_seq protection is unreliable and failing with hard error on what should've fallen back to non-RCU pathname resolution is a bug. Unfortunately, we'd pulled the test too far up and ran afoul of another kind of staleness. The dentry might have been absolutely stable from the RCU point of view (and we might be on UP, etc), but stale from the remote fs point of view. If ->d_revalidate() returns "it's actually stale", dentry gets thrown away and the original code wouldn't even have looked at its ->d_flags. What we need is to check ->d_flags where 766c4cbfacd8 does (prior to ->d_seq validation) but only use the result in cases where we do not discard this dentry outright" Reported-by: Leandro Awa <lawa@nvidia.com> Link: https://bugzilla.kernel.org/show_bug.cgi?id=104911 Fixes: 766c4cbfacd8 ("namei: d_is_negative() should be checked...")
