[PATCH] netfs: Pass flags through to grab_cache_page_write_begin()
From: David Howells <dhowells@redhat.com>
Date: 2021-05-13 10:49:30
Also in:
ceph-devel, linux-cifs, linux-fsdevel, linux-nfs
Subsystem:
filesystems (vfs and infrastructure), filesystems [netfs library], the rest · Maintainers:
Alexander Viro, Christian Brauner, David Howells, Paulo Alcantara, Linus Torvalds
In netfs_write_begin(), pass the AOP flags through to
grab_cache_page_write_begin() so that a request to use GFP_NOFS is honoured.
Fixes: e1b1240c1ff5 ("netfs: Add write_begin helper")
