![]() If the 1st NONHEAD lcluster of a pcluster isn't CBLKCNT lcluster type
rather than a HEAD or PLAIN type instead, which means its pclustersize
_must_ be 1 lcluster (since its uncompressed size < 2 lclusters),
as illustrated below:
HEAD HEAD / PLAIN lcluster type
____________ ____________
|_:__________|_________:__| file data (uncompressed)
. .
.____________.
|____________| pcluster data (compressed)
Such on-disk case was explained before [1] but missed to be handled
properly in the runtime implementation.
It can be observed if manually generating 1 lcluster-sized pcluster
with 2 lclusters (thus CBLKCNT doesn't exist.) Let's fix it now.
