MFC r178243:

2008-08-01T09:46:19Z

Move the head of byte-level advisory lock list from the filesystem-specific vnode data to the struct vnode. Provide the default implementation for the vop_advlock and vop_advlockasync. Purge the locks on the vnode reclaim by using the lf_purgelocks(). The default implementation is augmented for the nfs and smbfs. In the nfs_advlock, push the Giant inside the nfs_dolock. Before the change, the vop_advlock and vop_advlockasync have taken the unlocked vnode and dereferenced the fs-private inode data, racing with with the vnode reclamation due to forced unmount. Now, the vop_getattr under the shared vnode lock is used to obtain the inode size, and later, in the lf_advlockasync, after locking the vnode interlock, the VI_DOOMED flag is checked to prevent an operation on the doomed vnode.

MFC: Fix a nit with the 'nofoo' options where 'foo' is mapped to 'nonofoo'

so that filesystems will consider 'nonofoo' a valid option.

Some times ago, vfs_getopts() was changed, so that it would set error to

2007-08-20T15:33:22Z

ENOENT if the option wasn't provided, instead of setting it to 0. xfs however didn't catch up on this, so it assumed something went bad if vfs_getopts() sets the error to non-zero, and just returns the error. Unbreak xfs mount by just ignoring the error if vfs_getopts() sets the error to ENOENT, as we should have sane defaults. Reviewed by: kan Approved by: re (rwatson) Tested by: rpaulo

On 6.x this works:

Eliminate now-unused SUSER_ALLOWJAIL arguments to priv_check_cred(); in

2007-06-12T00:12:01Z

some cases, move to priv_check() if it was an operation on a thread and no other flags were present. Eliminate caller-side jail exception checking (also now-unused); jail privilege exception code now goes solely in kern_jail.c. We can't yet eliminate suser() due to some cases in the KAME code where a privilege check is performed and then used in many different deferred paths. Do, however, move those prototypes to priv.h.

- Move rusage from being per-process in struct pstats to per-thread in

2007-06-01T01:12:45Z

td_ru. This removes the requirement for per-process synchronization in statclock() and mi_switch(). This was previously supported by sched_lock which is going away. All modifications to rusage are now done in the context of the owning thread. reads proceed without locks. - Aggregate exiting threads rusage in thread_exit() such that the exiting thread's rusage is not lost. - Provide a new routine, rufetch() to fetch an aggregate of all rusage structures from all threads in a process. This routine must be used in any place requiring a rusage from a process prior to it's exit. The exited process's rusage is still available via p_ru. - Aggregate tick statistics only on demand via rufetch() or when a thread exits. Tick statistics are kept in the thread and protected by sched_lock until it exits. Initial patch by: attilio Reviewed by: attilio, bde (some objections), arch (mostly silent)
