Add several new test cases which assert corner cases on the eventfd mechanism, for example, the supplied buffer is less than 8 bytes, attempting to write a value that is too large, etc. ./eventfd_test # Starting 9 tests from 1 test cases. # RUN global.eventfd_check_flag_rdwr ... # OK global.eventfd_check_flag_rdwr ok 1 global.eventfd_check_flag_rdwr # RUN global.eventfd_check_flag_cloexec ... # OK global.eventfd_check_flag_cloexec ok 2 global.eventfd_check_flag_cloexec # RUN global.eventfd_check_flag_nonblock ... # OK global.eventfd_check_flag_nonblock ok 3 global.eventfd_check_flag_nonblock # RUN global.eventfd_chek_flag_cloexec_and_nonblock ... # OK global.eventfd_chek_flag_cloexec_and_nonblock ok 4 global.eventfd_chek_flag_cloexec_and_nonblock # RUN global.eventfd_check_flag_semaphore ... # OK global.eventfd_check_flag_semaphore ok 5 global.eventfd_check_flag_semaphore # RUN global.eventfd_check_write ... # OK global.eventfd_check_write ok 6 global.eventfd_check_write # RUN global.eventfd_check_read ... # OK global.eventfd_check_read ok 7 global.eventfd_check_read # RUN global.eventfd_check_read_with_nonsemaphore ... # OK global.eventfd_check_read_with_nonsemaphore ok 8 global.eventfd_check_read_with_nonsemaphore # RUN global.eventfd_check_read_with_semaphore ... # OK global.eventfd_check_read_with_semaphore ok 9 global.eventfd_check_read_with_semaphore # PASSED: 9 / 9 tests passed. # Totals: pass:9 fail:0 xfail:0 xpass:0 skip:0 error:0 Link: https://lkml.kernel.org/r/20240527000200.5615-1-wen.yang@linux.dev Signed-off-by: Wen Yang <wen.yang@linux.dev> Cc: Shuah Khan <shuah@kernel.org> Cc: Christian Brauner <brauner@kernel.org> Cc: Andrei Vagin <avagin@google.com> Cc: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Dave Young <dyoung@redhat.com> Cc: Tim Bird <tim.bird@sony.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
