tkusumi 819d266ed5 autofs: Make autofs(5) timeout messages include affected process name and PID 
Sync warning message with FreeBSD and DragonFlyBSD.
taken-from: FreeBSD

pgoyette 9120d4511b Use the module subsystem's ability to process SYSCTL_SETUP() entries to 
automate installation of sysctl nodes.

Note that there are still a number of device and pseudo-device modules
that create entries tied to individual device units, rather than to the
module itself.  These are not changed.

ad d39cb654b8 tmpfs_inactive(): do like other file systems and truncate the file if it 
has been deleted.  Otherwise VFS will try to write cached data "back to
disc", which in the case of a UAO means needless page deactivations and
the resulting TLB shootdowns.
 2020-03-14 13:39:36 +00:00
ad f1944288ff tmpfs_reg_resize(): do nothing if newsize == oldsize. 2020-03-14 13:37:49 +00:00
riastradh df1f0e7940 Revert "Include opt_diagnostic.h for DIAGNOSTIC." 
This did not do what I thought it did.  opt_diagnostic.h is only for
the unused _DIAGNOSTIC, which seems like an abortive attempt to
incrementally convert DIAGNOSTIC to an opt_*.h option rather than a
command-line option.
 2020-03-05 15:18:54 +00:00
riastradh 57c472be02 Include opt_diagnostic.h for DIAGNOSTIC. 
...at least, in header files, which may not have already included
libkern.h.

kamil 3fcf6843f7 Avoid undefined behavior in left shift semantics

ad bf79731039 Tighten up the locking around vp->v_iflag a little more after the recent 
split of vmobjlock & v_interlock.
 2020-02-27 22:12:53 +00:00
ad d2a0ebb67a UVM locking changes, proposed on tech-kern: 
- Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock.
- Break v_interlock and vmobjlock apart.  v_interlock remains a mutex.
- Do partial PV list locking in the x86 pmap.  Others to follow later.
 2020-02-23 15:46:38 +00:00
ad c2e9cb9413 VFS_VGET(), VFS_ROOT(), VFS_FHTOVP(): give them a "int lktype" argument, to 
allow us to get shared locks (or no lock) on the returned vnode.  Matches
FreeBSD.
 2020-01-17 20:08:06 +00:00
thorpej d6c967bb85 - Eliminate the global "boottime" variable, which was being accessed 
without any synchronization against changes by e.g. clock_settime().
- Replace with new getbinboottime() / getnanoboottime() / getmicroboottime()
  functions (naming mirrors that of other time access functions in kern_tc.c).
  It returns the (maybe-converted) value of timebasebin, which also tracks
  our estimate of when the system was booted (i.e. the legacy "boottime" was
  redundant).

XXX There needs to be a lockless synchronization mechanism for reading
timebasebin, but this is a problem in kern_tc.c that pre-existed these
"boottime" changes.  At least now the problem is centralized in one location.

tkusumi d3d26a328b autofs: Make /dev/autofs cdevsw functions static 
Also less confusing since autofs vnops also has autofs_{open,close} in NetBSD.
 2019-12-14 12:01:13 +00:00
pgoyette 8a031a1d1e Rather than keeping a separate mutex, condvar, and pserialize for each 
module hook, we can share a common set of synchronization structures.
This cuts the amount of cacheline_aligned data for these structures by
50%.

Note that we still have a per-hook localcount, since we need to count
individual references.

As discussed with riastradh@
