Xiao Chen updated HDFS-11904:
-----------------------------
Description:
In HDFS-10939, {{unprotectedSetXAttrs}} was optimized to use IIP instead of
path string.
This jira is to do the same on {{unprotectedRemoveXAttrs}}.
No performance test specifically for this is done yet, but it's not hard to see
a usage pattern of frequent removexattr could induce perf issues.
