remove CONFIG_ANDROID

2022-07-01T08:41:09Z

The ANDROID config symbol is only used to guard the binder config symbol and to inject completely random config changes. Remove it as it is obviously a bad idea. Acked-by: Paul E.

selftests/filesystems: add a vfat RENAME_EXCHANGE test

2022-06-17T02:58:22Z

Add a test for the renameat2 RENAME_EXCHANGE support in vfat, but split it in a tool that just does the rename exchange and a script that is run by the kselftests framework on `make TARGETS="filesystems/fat" kselftest`. That way the script can be easily extended to test other file operations. The script creates a 1 MiB disk image, that is then formated with a vfat filesystem and mounted using a loop device. That way all file operations are done on an ephemeral filesystem.

Pull char / misc / other smaller driver subsystem updates from Greg KH: "Here is the large set of char, misc, and other driver subsystem updates for 5.19-rc1. The merge request for this has been delayed as I wanted to get lots of linux-next testing due to some late arrivals of changes for the habannalabs driver. Highlights of this merge are: - habanalabs driver updates for new hardware types and fixes and other updates - IIO driver tree merge which includes loads of new IIO drivers and cleanups and additions - PHY driver tree merge with new drivers and small updates to existing ones - interconnect driver tree merge with fixes and updates - soundwire driver tree merge with some small fixes - coresight driver tree merge with small fixes and updates - mhi bus driver tree merge with lots of updates and new device support - firmware driver updates - fpga driver updates - lkdtm driver updates (with a merge conflict, more on that below) - extcon driver tree merge with small updates - lots of other tiny driver updates and fixes and cleanups, full details in the shortlog.

binderfs: add extended_error feature entry

2022-05-09T13:43:24Z

Add extended_error to the binderfs feature list, to help userspace determine whether the BINDER_GET_EXTENDED_ERROR ioctl is supported by the binder driver.

selftests/binderfs: Improve message to provide more info

2022-04-25T16:04:42Z

Currently the binderfs test says what failure it encountered without saying why it may occurred when it fails to mount binderfs. So, Warn about enabling CONFIG_ANDROID_BINDERFS in the running kernel.

selftests/binderfs: add test for feature files

kselftest: introduce new epoll test case

2021-05-07T02:24:13Z

Patch series "fs/epoll: restore user-visible behavior upon event ready". This series tries to address a change in user visible behavior, reported in https://bugzilla.kernel.org/show_bug.cgi?id=208943. Epoll does not report an event to all the threads running epoll_wait() on the same epoll descriptor. Unsurprisingly, this was bisected back to 339ddb53d373 (fs/epoll: remove unnecessary wakeups of nested epoll), which has had various problems in the past, beyond only nested epoll usage. This patch (of 2): This incorporates the testcase originally reported in: https://bugzilla.kernel.org/show_bug.cgi?id=208943 Which ensures an event is reported to all threads blocked on the same epoll descriptor, otherwise only a single thread will receive the wakeup once the event become ready.
