Subject: [PATCH 1/4] linux 6.7 compat: simplify current_time() check
6.7 changed the names of the time members in struct inode, so we can't
assign back to it because we don't know its name. In practice this
doesn't matter though - if we're missing current_time(), then we must be
on <4.9, and we know our fallback will need to return timespec.

Subject: [PATCH 2/4] linux 6.7 compat: use inode atime/mtime accessors
6.6 made i_ctime inaccessible; 6.7 has done the same for i_atime and
i_mtime. This extends the method used for ctime in b37f29341 to atime
and mtime as well.

Subject: [PATCH 3/4] linux 6.7 compat: handle superblock shrinker member
change
In 6.7 the superblock shrinker member s_shrink has changed from being an
embedded struct to a pointer. Detect this, and don't take a reference if
it already is one.

Subject: [PATCH 4/4] linux 6.7 compat: rework shrinker setup for heap
allocations
6.7 changes the shrinker API such that shrinkers must be allocated
dynamically by the kernel. To accomodate this, this commit reworks
spl_register_shrinker() to do something similar against earlier kernels.

Previously, we only checked if the times changed at all, which missed a
bug where the atime was being set to an undefined value.
Now ensure the times change by two seconds (or thereabouts), ensuring we
catch cases where we set the time to something bonkers

Subject: [PATCH 2/2] zfs_setattr: fix atime update
In db4fc559c I messed up and changed this bit of code to set the inode
atime to an uninitialised value, when actually it was just supposed to
loading the atime from the inode to be stored in the SA. This changes it
to what it should have been.
