Disable stat() caching so changes to the backing storage show up + immediately. +2. Disable hard link tracking, as the inode numbers on the backing + storage are not stable when files are deleted and re-created behind + our back. This would otherwise produce strange "file does not exist" + and other errors. + +When "-sharedstorage" is active, performance is reduced and hard +links cannot be created. + +Even with this flag set, you may hit occasional problems. Running +gocryptfs on shared storage does not receive as much testing as the +usual (exclusive) use-case. Please test your workload in advance +and report any problems you may hit. + +More info: https://github.com/rfjakob/gocryptfs/issues/156 + #### -speed Run crypto speed test.
