Please note that sysfs is not the only one to do this. A quick peek reveals XFS and CIFS returing ENOMEM for write() and there are probably others as well. Perhaps we should replace ENOMEM with ENOBUFS in vfs_write() instead?
linvfs_write xfs_write xfs_zero_eof xfs_zero_last_block xfs_iozero -> Returns -ENOMEM
cifs_user_write cifs_reopen_file -> Returns -ENOMEM
