--------------------------------
Following are the functions where it has done the resolution
{{fsd.resolvePath(pc, src, pathComponents);}} by acquiring only fsn lock and
not fsd lock. Could you please take a look at it.
# FsDirAclOp.java
-> getAclStatus()
-> modifyAclEntries()
-> removeAcl()
-> removeDefaultAcl()
-> setAcl()
-> getAclStatus()
# FsDirDeleteOp.java
-> delete(fsn, src, recursive, logRetryCache)
# FsDirRenameOp.java
-> renameToInt(fsd, srcArg, dstArg, logRetryCache)
-> renameToInt(fsd, srcArg, dstArg, logRetryCache, options)
# FsDirStatAndListingOp.java
-> getContentSummary(fsd, src)
-> getFileInfo(fsd, srcArg, resolveLink)
-> isFileClosed(fsd, src)
-> getListingInt(fsd, srcArg, startAfter, needLocation)
# FsDirWriteFileOp.java
-> abandonBlock()
-> completeFile(fsn, pc, srcArg, holder, last, fileId)
-> getEncryptionKeyInfo(fsn, pc, src, supportedVersions)
-> startFile()
-> validateAddBlock()
# FsDirXAttrOp.java
-> getXAttrs(fsd, srcArg, xAttrs)
-> listXAttrs(fsd, src)
-> setXAttr(fsd, src, xAttr, flag, logRetryCache)
# FSNamesystem.java
-> createEncryptionZoneInt()
-> getEZForPath()
> Consolidate truncate() related implementation in a single class
