Hi Linus,
Please pull these kmalloc_obj() conversions for v7.3-rc2.
If this is too late in the cycle, no worries, I'll wait and do it in the
second week of the v7.4 merge window for its -rc1. I only discovered
earlier this week that Coccinelle had missed a bunch in the v7.0
tree-wide conversions due to its (silent) failure to parse functions
using scope_guard() and family[1]. Since -rc2 hadn't cut yet, I thought
if you wanted these now, I could get them to you.
Anyway, here's the commit log repeated:
This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci
This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.
Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.
