+Subject: [PATCH] btf: Remove ftrace filter
+
+BTF is currently generated for functions that are in ftrace list
+or extern.
+
+A recent use case also needs BTF generated for functions included in
+allowlist.
+
+In particular, the kernel commit:
+
+ e78aea8b2170 ("bpf: tcp: Put some tcp cong functions in allowlist for bpf-tcp-cc")
+
+allows bpf program to directly call a few tcp cc kernel functions. Those
+kernel functions are currently allowed only if CONFIG_DYNAMIC_FTRACE
+is set to ensure they are in the ftrace list but this kconfig dependency
+is unnecessary.
+
+Those kernel functions are specified under an ELF section .BTF_ids.
+There was an earlier attempt [0] to add another filter for the functions in
+the .BTF_ids section. That discussion concluded that the ftrace filter
+should be removed instead.
+
+This patch is to remove the ftrace filter and its related functions.
+
+Number of BTF FUNC with and without is_ftrace_func():
+My kconfig in x86: 40643 vs 46225
+Jiri reported on arm: 25022 vs 55812

+%description
+dwarves is a set of tools that use the debugging information inserted in
+ELF binaries by compilers such as GCC, used by well known debuggers such as
+GDB, and more recent ones such as systemtap.
+
+Utilities in the dwarves suite include pahole, that can be used to find
+alignment holes in structs and classes in languages such as C, C++, but not
+limited to these.
+
+It also extracts other information such as CPU cacheline alignment, helping
+pack those structures to achieve more cache hits.
+
+These tools can also be used to encode and read the BTF type information format
+used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'.
+
+A diff like tool, codiff can be used to compare the effects changes in source
+code generate on the resulting binaries.
+
+Another tool is pfunct, that can be used to find all sorts of information about
+functions, inlines, decisions made by the compiler about inlining, etc.
+
+One example of pfunct usage is in the fullcircle tool, a shell that drivers
+pfunct to generate compileable code out of a .o file and then build it using
+gcc, with the same compiler flags, and then use codiff to make sure the
+original .o file and the new one generated from debug info produces the same
+debug info.
+
+Pahole also can be used to use all this type information to pretty print raw data
+according to command line directions.
+
+Headers can have its data format described from debugging info and offsets from
+it can be used to further format a number of records.
+
+The btfdiff utility compares the output of pahole from BTF and DWARF to make
+sure they produce the same results.
