+Subject: [PATCH] QATAPP-32528: Fixed the qzip decompress large file issue
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+Content-type: text/plain
+
+* The “bytes_processed” only updated when “DATA_ERROR/BUF_ERROR”
+happened. It’s OK if during each “src buffer”, it would run into
+“DATA_ERROR/BUF_ERROR” (This is the majority of cases, for 512M
+src buffer, it almost always have “incomplete source buffer”
+return). It’s also ok, if for each “src buffer”, it never run into
+“DATA_ERROR/BUF_ERROR”, so it wouldn’t call “fseek”,
+then bytes_processed is useless. But, if we mix those tow scenarios,
+For some “src buffer” run into “DATA_ERROR/BUF_ERROR” and
+others don’t. Then “bytes_processed” will miss some process
+source for which complete decompression without error issue.
+It cause the “fseek” set to incorrect file stream position.
