Hi all, For the last week we've been having consistent issues with CIFS mounts on our AWS WorkSpaces running Amazon Linux 2. Any time a file is overwritten, the entire mount point breaks. Reading, creating and deleting files still works. For example, "git clone <remote_repo>" is fine, as is "rm -r <local_repo>", but "git checkout <branch>" hangs uninterruptibly, as does "git add <file>". When there are hanging processes, the mount point becomes entirely unreachable: attempts to umount return a segfault, attempts to "ls" the directory that contains them or tab complete their directory names will hang the terminal (and sometimes kill the terminal process), and lsof returns a "can't stat filesystem" error and hangs until interrupted. The one consistency between the affected machines is that problems began after upgrading kernel from 4.14.114 to 4.14.121, and that these issues do not occur when we boot into the previous kernel. Is this a known issue, and if so is there an estimate on when a fix might be released?
