Subject: NFS: Return -ETXTBSY when attempting to write to a swapfile
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=89658c4d04c7661c2c0770c6f92f465d58eed62d;p=linux.git

NFS: Return -ETXTBSY when attempting to write to a swapfile

My understanding is that -EBUSY refers to the underlying device, and
that -ETXTBSY is used when attempting to access a file in use by the
kernel (like a swapfile). Changing this return code helps us pass
xfstests generic/569
