 to the cache

Hi,

This patch needs to be included into the release along with the ea_inode feature to maintain proper feature compatibility with Lustre.
Could it be landed as soon as possible?

Thanks,
Emoly

For Lustre, if ea_inode fails in hash validation but passes parent inode and generation checks, it won't be added to the cache as well as the error "-EFSCORRUPTED" should be cleared, otherwise it will cause "Structure needs cleaning" when running getfattr command.
