Subject: [PATCH v3 15/33] afs: Fix directory format encoding struct
Date: Wed,  6 Nov 2024 12:35:39 +0000	[thread overview]
Message-ID: <20241106123559.724888-16-dhowells@redhat.com> (raw)
In-Reply-To: <20241106123559.724888-1-dhowells@redhat.com>

The AFS directory format structure, union afs_xdr_dir_block::meta, has too
many alloc counter slots declared and so pushes the hash table along and
over the data.  This doesn't cause a problem at the moment because I'm
currently ignoring the hash table and only using the correct number of
alloc_ctrs in the code anyway.  In future, however, I should start using
the hash table to try and speed up afs_lookup().

Fix this by using the correct constant to declare the counter array.

Fixes: 4ea219a839bf ("afs: Split the directory content defs into a header")
