| H A D | file.c | ddeff520 Wed Aug 09 12:53:47 CDT 2006 Nikita Danilov <nikita@clusterfs.com> NFS: Fix a potential deadlock in nfs_release_page
nfs_wb_page() waits on request completion and, as a result, is not safe to be
called from nfs_release_page() invoked by VM scanner as part of GFP_NOFS
allocation. Fix possible deadlock by analyzing gfp mask and refusing to
release page if __GFP_FS is not set.
