SYNOPSIS
typedef handle_t;
DESCRIPTION
All filesystem modifications made by the process go through this handle. Recursive operations (such as quota operations) are gathered into a single update.
The buffer credits field is used to account for journaled buffers being modified by the running process. To ensure that there is enough log space for all outstanding operations, we need to limit the number of outstanding buffers possible at any time. When the operation completes, any buffer credits not used are credited back to the transaction, so that at all times we know how many buffers the outstanding updates on a transaction might possibly touch.
This is an opaque datatype.
