* There are 2 types of mutexes:
*
* * Adaptive -- If the lock is already held, the thread attempting
* to acquire the lock determines if the thread that holds it is
* currently running. If so, it spins, else it sleeps.
*
* * Spin -- If the lock is already held, the thread attempting to
* acquire the lock spins. The IPL will be raised on entry.
*
* Machine dependent code must provide the following:
*
* struct mutex
* The actual mutex structure. This structure is mostly
* opaque to machine-independent code; most access are done
* through macros. However, machine-independent code must
* be able to access the following members:
*
* uintptr_t mtx_owner
* ipl_cookie_t mtx_ipl
* __cpu_simple_lock_t mtx_lock
*
* If an architecture can be considered 'simple' (no interlock required in
* the MP case, or no MP) it need only define __HAVE_SIMPLE_MUTEXES and
* provide the following:
*
* struct mutex
*
* [additionally:]
* volatile integer mtx_id
*
* MUTEX_RECEIVE(mtx)
* Post a load fence after acquiring the mutex, if necessary.
*
* MUTEX_GIVE(mtx)
* Post a load/store fence after releasing the mutex, if
* necessary.
*
* MUTEX_CAS(ptr, old, new)
* Perform an atomic "compare and swap" operation and
* evaluate to true or false according to the success
*
* Otherwise, the following must be defined:
*
* MUTEX_INITIALIZE_SPIN(mtx, dodebug, minipl)
* Initialize a spin mutex.
*
* MUTEX_INITIALIZE_ADAPTIVE(mtx, dodebug)
* Initialize an adaptive mutex.
*
* MUTEX_DESTROY(mtx)
* Tear down a mutex.
*
* MUTEX_ADAPTIVE_P(mtx)
* Evaluates to true if the mutex is an adaptive mutex.
*
* MUTEX_SPIN_P(mtx)
* Evaluates to true if the mutex is a spin mutex.
*
* MUTEX_OWNER(owner)
* Returns the owner of the adaptive mutex (LWP address).
*
* MUTEX_OWNED(owner)
* Returns non-zero if an adaptive mutex is currently
* held by an LWP.
*
* MUTEX_HAS_WAITERS(mtx)
* Returns true if the mutex has waiters.
*
* MUTEX_SET_WAITERS(mtx)
* Mark the mutex has having waiters.
*
* MUTEX_ACQUIRE(mtx, owner)
* Try to acquire an adaptive mutex such that:
* if (lock held OR waiters)
* return 0;
* else
* return 1;
* Must be MP/interrupt atomic.
*
* MUTEX_RELEASE(mtx)
* Release the lock and clear the "has waiters" indication.
* Must be interrupt atomic, need not be MP safe.
*
* MUTEX_DEBUG_P(mtx)
* Evaluates to true if the mutex is initialized with
* dodebug==true. Only used in the LOCKDEBUG case.
*
* Machine dependent code may optionally provide stubs for the following
* functions to implement the easy (unlocked / no waiters) cases. If
* these stubs are provided, __HAVE_MUTEX_STUBS should be defined.
*
* mutex_enter()
* mutex_exit()
*
* Two additional stubs may be implemented that handle only the spinlock
* case, primarily for the scheduler. __HAVE_SPIN_MUTEX_STUBS should be
* defined if these are provided:
*
* mutex_spin_enter()
* mutex_spin_exit()

.Sh NAME
.Nm fsck
.Nd file system consistency check and interactive repair
.Sh SYNOPSIS
.Nm
.Op Fl dfnPpqvy
.Op Fl l Ar maxparallel
.Op Fl T Ar fstype:fsoptions
.Op Fl t Ar fstype
.Op Fl x Ar mountpoint
.Op special | node ...
.Sh DESCRIPTION
The
.Nm
command invokes file system-specific programs to check
the special devices listed in the
.Xr fstab 5
file or in the command line for consistency.
.Pp
It is normally used in the script
.Pa /etc/rc
during automatic reboot.
If no file systems are specified, and
.Dq preen
mode is enabled (
.Fl p
option)
.Nm
reads the table
.Pa /etc/fstab
to determine which file systems to check, in what order.
Only partitions in fstab that are mounted ``rw,'' ``rq'' or ``ro''
and that have non-zero pass number are checked.
File systems with pass number 1 (normally just the root file system)
are checked one at a time.
When pass 1 completes, all remaining file systems are checked,
running one process per disk drive.
By default, file systems which are already mounted read-write are not checked.
The disk drive containing each file system is inferred from the longest prefix
of the device name that ends in a digit; the remaining characters are assumed
to be the partition designator.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl d
Debugging mode.
Just print the commands without executing them.
.It Fl f
Force checking of file systems, even when they are marked clean (for file
systems that support this), or when they are mounted read-write.
.It Fl l Ar maxparallel
Limit the number of parallel checks to the number specified in
the following argument.
By default, the limit is the number of disks, running one process per disk.
If a smaller limit is given, the disks are checked round-robin,
one file system at a time.
.It Fl n
Causes
.Nm
to assume no as the answer to all operator questions, except "CONTINUE?".
.It Fl P
Display a progress meter for each file system check.
This option also disables parallel checking.
Note that progress meters are not supported by all file system types.
.It Fl p
Enter preen mode.
In preen mode,
.Nm
will check all file systems listed in
.Pa /etc/fstab
according to their pass number, and will make minor repairs without
human intervention.
.It Fl q
Quiet mode, do not output any messages for clean filesystems.
.It Fl T Ar fstype:fsoptions
List of comma separated file system specific options for the specified
file system type, in the same format as
.Xr mount 8 .
.It Fl t Ar fstype
Invoke
.Nm
only for the comma separated list of file system types.
If the list starts with
.Dq no
then invoke
.Nm
for the file system types that are not specified in the list.
.It Fl v
Print the commands before executing them.
.It Fl x Ar mountpoint
Exclude the filesystem which has a
.Ar mountpoint
the same as in
.Pa /etc/fstab .
Used only in
.Dq preen
mode.
.It Fl y
Causes
.Nm
to assume yes
as the answer to all operator questions.
.El
.Sh FILES
.Bl -tag -width /etc/fstab -compact
.It Pa /etc/fstab
file system table
.El
.Sh EXIT STATUS
.Nm
exits with
.Dv 0
on success.
Any major problems will cause
.Nm
to exit with the following non-zero
.Xr exit 3
codes, so as to alert any invoking program or script that human
intervention is required.
.Bl -tag -width XXXX
.It Dv 1
Usage problem.
.It Dv 2
Unresolved errors while checking the filesystem.
Re-running
.Nm
on the filesystem(s) is required.
.It Dv 4
The root filesystem was changed in the process of checking, and updating the
mount was unsuccessful.
A reboot (without sync) is required.
.It Dv 8
The filesystem check has failed, and a subsequent check is required
that will require human intervention.
.It Dv 12
.Nm
exited because of the result of a signal (usually
.Dv SIGINT
or
.Dv SIGQUIT
from the terminal).
