X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6899320c2cefe5ae6b606f820ba8b762ba21f34a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] knfsd: nfsd: simplify exp_pseudoroot

Note there's no need for special handling of -EAGAIN here; nfserrno() does
what we want already.  So this is a pure cleanup with no change in
functionality.
