/** mkquota.h
 *
 * Interface to the quota library.
 *
 * The quota library provides interface for creating and updating the quota
 * files and the ext4 superblock fields. It supports the new VFS_V1 quota
 * format. The quota library also provides support for keeping track of quotas
 * in memory.
 * The typical way to use the quota library is as follows:
 * {
 *	quota_ctx_t qctx;
 *
 *	quota_init_context(&qctx, fs, -1);
 *	{
 *		quota_compute_usage(qctx, -1);
 *		AND/OR
 *		quota_data_add/quota_data_sub/quota_data_inodes();
 *	}
 *	quota_write_inode(qctx, USRQUOTA);
 *	quota_write_inode(qctx, GRPQUOTA);
 *	quota_release_context(&qctx);
 * }
 *
 * This initial version does not support reading the quota files. This support
 * will be added in near future.
