Since ~v6.5-rc1-95-g0d72b92883c6, generic_fillattr() asks us to pass
through the request_mask from the caller. This allows it to only
request a subset.

Yet another major shrinker API evolution in v6.6-rc4-53-gc42d50aefd17.
The struct shrinker now has to be dynamically allocated. This is
purposely a backwards incompatible break.
Collapse the previous KC_ALLOC_SHRINKER, KC_INIT_SHRINKER_FUNCS,
and KC_REGISTER_SHRINKER macros into a single KC_SETUP_SHRINKER
macro. The three operations have to happen in different orders on
different kernel APIs (the name is needed at alloc time on el10
and at register time on KC_SHRINKER_NAME kernels), so coupling
them keeps the ordering correct per kernel.
Add KC_SHRINKER_IS_NULL so callers can detect shrinker_alloc()
failure on el10 and return -ENOMEM. The macro compiles to a
constant 0 on older kernels where the shrinker is an embedded
struct that cannot fail allocation.

The return type always has been int, so, we just need to add return
value checking and do something with it. We could return -ENOMEM here as
well, either way it'll fall all the way through no matter what.
This is since v6.4-rc2-100-g83f2caaaf9cb.

In v6.8-9146-gc759e609030c, the second argument for __assign_str() was
removed, as the second parameter is already derived from the __string()
definition and no longer needed. We have to do a little digging in
headers here to find the definition.
Note the missing `;` at a few places... it has to be added now.

v6.9-rc4-29-g203c1ce0bb06 removes bd_inode. The canonical replacement is
bd_mapping->host, where applicable. We have one use where we directly
need the mapping instead of the inode, as well.

Instead of defining a struct that ends with a flex array member with
`val[0]`, the compiler now balks at this since technically, the spec
considers this unsanitary. As a result however, we can't memcpy to
`struct->val` since that's a pointer and now we're writing something of
a different length (u8's in our case) into something that's of pointer
size. So there we have to do the opposite, and memcpy to
&struct->val[0].

In v6.12-rc1-3-g5f60d5f6bbc1, asm/unaligned.h only included
asm-generic/unaligned.h and that was cleaned up from architecture
specific things. Everyone should now include linux/unaligned.h and the
former include was removed.
A quick peek at server.c shows that while included, it no longer uses
any function from this header at all, so it can just be dropped.

In v6.6-rc5-1-g077c212f0344, one can no longer directly access the
inode m_time and a_time etc. We have to go through these static inline
functions to get to them.
Further back, ctime accessors were added in v6.5-rc1-7-g9b6304c1d537,
and need to be applied as well.

In v6.1-rc5-2-ge9a688bcb193, get_random_u32_below() becomes available and
can start replacing prandom_bytes_max(). Switch to it where we can.
get_random_bytes() has been available since el7, so also replace
prandom_bytes() where we're using it.

In RHEL10, the grep version is bumped from 3.6 to 3.11, and grep
no longer recognizes the \Z character anymore.
We have 2 solutions: We can either choose to use `grep -P` to
continue using it, or, alternatively, we can choose a different
`null` match to have an effectively empty exclude list.
The latter seems easy enough: By default, we can just exclude
empty lines ("^$") obtaining the exact same behavior as before.

This is somewhat cumbersome, we want to see the error message, but the
format changes enough to make this messy. We opt to change the golden to
the new format, which only shows one of the arguments in its error
output: the thing that cannot be overwritten. We then add a filter that
rewrites the old output format with sed patterns to be exactly like the
new format, so this will work everywhere again, without changing or
adding filters to obscure error messages.

The new format in el10 has non-hex output, separated by a comma. Add the
additional filter string so this works as expected.

RHEL7 was the only conditional user of this define, but since

scoutfs_rename2 was a thin shim that validated flags and forwarded
to scoutfs_rename_common. It existed because the old el7
RHEL_IOPS_WRAPPER path used a non-flag-taking .rename op alongside
.rename2; with that path gone there is only one rename method,
and the wrapper has no purpose.
Move the RENAME_NOREPLACE flag validation into scoutfs_rename_common
and point the directory inode_operations .rename slot at it directly.
The symlink inode_operations already used scoutfs_rename_common, so
this also makes symlink rename consistently reject unknown flags
instead of silently accepting them.

el8 already provides stack_trace_save() and stack_trace_print()

el8 already provides vm_fault_t and vmf_error(), so the fallback

no longer is el7 support. Remove the test.
