Subject [jira] [Commented] (HDFS-3306) fuse_dfs: don't lock release operations
Date Thu, 26 Apr 2012 02:01:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3306?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262315#comment-13262315

Eli Collins commented on HDFS-3306:
-----------------------------------

Check the parallel case, eg multiple threads cat'ing the same set of files in parallel (will
result in open/release on the same files)?

> There's no need to lock release operations in FUSE, because release can only be called
once on a fuse_file_info structure.
