Author: dchagin Date: Sun Feb 15 21:50:08 2015 New Revision: 278821 URL: https://svnweb.freebsd.org/changeset/base/278821 Log: To allow reading pseudofs files by chunks replace sbuf from fixed to autoextend. The problem appears when the user tries to read a small chunk of the pseudofs file. The underlying fill method will fail if the size of the supplied sbuf sb is less than required to contain method data.
