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
