This reverts commit e571e029bdbf ("perf tools: Enable indices setting syntax for BPF map"). The reverted commit added a notion of arrays that could be set as event terms for BPF events. The parsing hasn't worked over multiple Linux releases. Given the broken nature of the parsing it appears the code isn't in use, nor could I find a way for it to be used to add a test. The original commit contains a test in the commit message, however, running it yields: ``` $ perf record -e './test_bpf_map_3.c/map:channel.value[0,1,2,3...5]=101/' usleep 2 event syntax error: '..pf_map_3.c/map:channel.value[0,1,2,3...5]=101/' \___ parser error Run 'perf list' for a list of valid events Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -e, --event <event> event selector. use 'perf list' to list available events ``` Given the code can't be used this commit reverts and removes it.

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 Restructured Text 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.
