Subject: NFS: don't expect errors from mempool_alloc().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=237f8306c30206d997e265ff46652e602a50824f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

NFS: don't expect errors from mempool_alloc().

Commit fbe77c30e9ab ("NFS: move rw_mode to nfs_pageio_header")
reintroduced some pointless code that commit 518662e0fcb9 ("NFS: fix
usage of mempools.") had recently removed.

Remove it again.
