We already have a helper lruvec_memcg() to get the memcg from lruvec, we
do not need to do it ourselves in the lruvec_holds_page_lru_lock(). So use
lruvec_memcg() instead. And if mem_cgroup_disabled() returns false, the
page_memcg(page) (the LRU pages) cannot be NULL. So remove the odd logic
of "me
All the callers of mem_cgroup_page_lruvec() just pass page_pgdat(page)
as the 2nd parameter to it (except isolate_migratepages_block()). But
for isolate_migratepages_block(), the page_pgdat(page) is also equal
to the local variable of @pgdat. So mem_cgroup_page_lruvec() do not
need the pgdat parame
When mm is NULL, we do not need to hold rcu lock and call css_tryget for
the root memcg. And we also do not need to check !mm in every loop of
while. So bail out early when !mm.

Hello Michael,
The latest version of this patch addressed all feedback I'm aware of
when submitted last September, and I've seen no further comments from
reviewers since then.
Could you please let me know where this stands and if anything further

Kind regards,

It's possible that an architecture may want to populate
boot_command_line before calling the device tree code.
Currently, early_init_dt_scan_chosen won't accept a NULL
in the data parameter and it returns immediately if you
send one.
I changed early_init_dt_scan_nodes() to send a NULL into
early_i
This adds code to handle the generic command line changes.
The efi code appears that it doesn't benefit as much from this design
as it could.
For example, if you had a prepend command line with "nokaslr" then
you might be helpful to re-enable it in the boot loader or dts,
but there appears to be n
This removes arm64 from the device tree handling of the
command line arguments.
The boot_command_line variable is populated inside the earliest
user of the command line, which is in idreg-override.c.
The device tree should not be needed to do any further handling
of the boot command line options.
This updates the x86 code to use the CONFIG_GENERIC_CMDLINE
option.

This deletes the option for MIPS_CMDLINE_BUILTIN_EXTEND

This code allows architectures to use a generic builtin command line.
The state of the builtin command line options across architecture is
diverse. MIPS and X86 once has similar systems, then mips added some
