Author: asomers Date: Thu Jan 16 21:31:56 2020 New Revision: 356809 URL: https://svnweb.freebsd.org/changeset/base/356809 Log: setextattr: Increase stdin buffer size to 4096 Extended attribute values can potentially be quite large. One test for ZFS is supposed to set a 200MB xattr. However, the buffer size for reading values from stdin with setextattr -i is so small that the test times out waiting for tiny chunks of data to be buffered and appended to an sbuf. Increasing the buffer size should help alleviate some of the burden of reallocating larger sbufs when writing large extended attributes.
