From: Amir Goldstein <amir73il@xxxxxxxxx>
[ Upstream commit 03f275adb8fbd7b4ebe96a1ad5044d8e602692dc ]
The re-factoring of fuse_dir_open() missed the need to invalidate
directory inode page cache with open flag FOPEN_KEEP_CACHE.
Fixes: 7de64d521bf92 ("fuse: break up fuse_open_common()")
Reported-by: Prince Kumar <princer@xxxxxxxxxx>
Closes: https://lore.kernel.org/linux-fsdevel/CAEW=TRr7CYb4LtsvQPLj-zx5Y+EYBmGfM24SuzwyDoGVNoKm7w@xxxxxxxxxxxxxx/
