[PATCH 3.14 183/238] fs/notify: dont show f_handle if exportfs_encode_inode_fh failed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrey Vagin <avagin@xxxxxxxxxx>

commit 7e8824816bda16bb11ff5ff1e1212d642e57b0b3 upstream.

Currently we handle only ENOSPC.  In case of other errors the file_handle
variable isn't filled properly and we will show a part of stack.
