.SH "DESCRIPTION"
.PP
Search for the inode specified by
\fIino\fR
in the inode cache and if present return it with an increased reference count\&. This is for file systems where the inode number is sufficient for unique identification of an inode\&.
.PP
If the inode is not in cache, allocate a new inode and return it locked, hashed, and with the I_NEW flag set\&. The file system gets to fill it in before unlocking it via
\fBunlock_new_inode\fR\&.
