Subject: LU-8259 osd-ldiskfs update all *_seq_write() to use "const char __user *buffer"
X-Git-Tag: 2.8.56~110
X-Git-Url: https://git.whamcloud.com/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F87%2F20887%2F2;p=fs%2Flustre-release.git

LU-8259 osd-ldiskfs update all *_seq_write() to use "const char __user *buffer"

All *_seq_write functions in lustre/osd-ldiskfs/osd_lproc.c declare
buffer as "const char *buffer" and should use "const char __user *buffer"
instead.

This patch takes care of this change.
