3987	Midnight Commander loses content of the current directory	memy	andrew_b	"When I am browsing a mounted SMB directory Midnight Commander sometimes loses directory content.
When I hit Ctrl-r the content of the directory reappears.

It started today after upgrading of the kernel and samba.
All other means of browsing file system work perfectly fine: shell, Thunar, File Open dialogs, etc.
I have shares mounted on different servers:

1. Synology NAS
2. Raspberry Pi 4.19.42-1-ARCH #1 SMP PREEMPT Wed May 15 00:39:47 UTC 2019 armv7l GNU/Linux
3. Dell mini 5.1.2-arch1-1-ARCH #1 SMP PREEMPT Wed May 15 00:09:47 UTC 2019 x86_64 GNU/Linux

MC demonstrates the same behavior on all of the shares.

When I browse to a directory on a mounted SMB share MC occasionally shows empty directory. Re-read immediately restores the panel. The same happens when I am returning back to the parent directory.

The shares are mounted at boot time using systemd like this but the problem persists with any other way of mounting the SMB share:

{{{

I run Arch Linux.
