VFS_QUOTACTL(9) FreeBSD Kernel Developer's Manual VFS_QUOTACTL(9)
NAME
VFS_QUOTACTL - manipulate file system quotas
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
#include <sys/vnode.h>
int
VFS_QUOTACTL(struct mount *mp, int cmds, uid_t uid, void *arg,
bool *mp_busy);
DESCRIPTION
Implement file system quotas.
The mp_busy argument is an input/output parameter. VFS_QUOTACTL() must
be called with mp marked busy through vfs_busy(9) and *mp_busy set to
true. The filesystem implementation of VFS_QUOTACTL() may then unbusy mp
using vfs_unbusy(9) prior to performing quota file I/O. In this case the
implementation must set *mp_busy to false to indicate that the caller
must not unbusy mp upon completion of VFS_QUOTACTL().
See quotactl(2) for a description of the remaining arguments.
