arch: Register fchmodat2, usually as syscall 452

2023-07-27T10:25:35+00:00

This registers the new fchmodat2 syscall in most places as nuber 452,
with alpha being the exception where it's 562.  I found all these sites
by grepping for fspick, which I assume has found me everything.

cachestat: wire up cachestat for other architectures

2023-06-09T23:25:16+00:00

cachestat is previously only wired in for x86 (and architectures using
the generic unistd.h table):

This patch wires cachestat in for all the other architectures.

exit/bdflush: Remove the deprecated bdflush system call

2021-07-12T20:17:47+00:00

The bdflush system call has been deprecated for a very long time.
Recently Michael Schmitz tested[1] and found that the last known
caller of of the bdflush system call is unaffected by it's removal.

Since the code is not needed delete it.

quota: Disable quotactl_path syscall

2021-05-17T12:39:56+00:00

In commit fa8b90070a80 ("quota: wire up quotactl_path") we have wired up
new quotactl_path syscall. However some people in LWN discussion have
objected that the path based syscall is missing dirfd and flags argument
which is mostly standard for contemporary path based syscalls. Indeed
they have a point and after a discussion with Christian Brauner and
Sascha Hauer I've decided to disable the syscall for now and update its
API. Since there is no userspace currently using that syscall and it
hasn't been released in any major release, we should be fine.
