Elide the fs-wide rename lock for single-directory renames. This
required changing the order of lookups, so that we know what the
directories are before we lock the nodes.
Clean up error branches, explain why various nonsense happens and
what it does and doesn't do, and note some of what needs to change.
fs/puffs/t_fuzz:mountfuzz7, fs/puffs/t_fuzz:mountfuzz8,
and fs/zfs/t_zpool:create tests pass again. Patch from
manu, discussed on tech-kern and committed at his request.
unsigned. They are signed. (While unsigned might have been a better
choice, it doesn't really matter and the majority of preexisting uses
were signed. And consistency is good.)
- struct vfs_quotactl_args -> struct quotactl_args
- add sys/stdint.h to sys/quotactl.h for clean userland build
- install sys/quotactl.h in /usr/include
- update set lists for same
- add new marshalling code in libquota
- add new unmarshalling code in vfs_syscalls.c
- discard proplib interpreter code in vfs_quotactl.c
- add dispatching code for the 14 quotactl ops in vfs_quotactl.c
- mark the proplib quotactl syscall obsolete
- add a new syscall number for the new quotactl syscall
- change the name of the syscall to __quotactl()
- remove the decl of the old quotactl from quota/quotaprop.h
- add a decl of the new quotactl to sys/quotactl.h
- update the libc build
- update ktruss
- remove proplib marshalling code from libquota
- update copy of syscall table in gdb ppc sources
- hack rumphijack to accomodate new quotactl name (as I recall,
pooka wanted such a name change to simplify something, but I
don't really see what/how)
This change appears to require a kernel version bump for rumpish
reasons.
the header file and use that.
- sort the list of basic flags
- add MNT_RELATIME, ST_RELATIME
- mask all the op flags, for symmetry.
The real bit difference is (which is harmless):
- mount was missing MNT_EXTATTR
- update sets MNT_RDONLY twice
- ops also could or in MNT_GETARGS, but this is impossible because the
code would have chosen to do getargs then.
to UTIMES_NOW, act as if NULL is passed to second argument, i.e.,
do same permission check and set exactly same value to both access
and modification time.
unimplemented, except enough of linkat(2) to hardlink to a symlink.
Everything new in headers is guarded #ifdef _INCOMPLETE_XOPEN_C063 since
some software (e.g.: xcvs in our own tree) will assume they can use openat(2)
when AT_FDCWD is defined. _INCOMPLETE_XOPEN_C063 will go away once support
will be completed.
for UFS1).
Remove kernel option for EA backing store autocreation and do it by
default. Add a sysctl so that autocreated attriutr size can be modified.
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.
add do_sys_sync() that takes an 'lwp' (for l_cred) as an argument.
Explicitly pass &lwp0 rather than NULL and expecting sys_sync to
substitute some random lwp.
already prevented). File systems are no longer responsible to check this.
Clean up and add asserts (note that dvp == vp cannot happen in vop_link).
OK dholland@
- Add fd_set_exclose() to encapsulate uses of FIO{,N}CLEX, O_CLOEXEC, F{G,S}ETFD
- Add a pipe1() function to allow passing flags to the fd's that pipe(2)
opens to ease implementation of linux pipe2(2)
- Factor out fp handling code from open(2) and fhopen(2)
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

calling VOP_ACCESS with flags 0 and something asserts deep in the
bowels of kauth. PR 44648 from Taylor Campbell. (I moved the check
earlier relative to the suggested patch.)
