Subject: LU-5954 IOC_MDC_GETFILEINFO returns the wrong ino
X-Git-Tag: 2.8.55~49
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=86158ae647b25338489bcb3181f29081f1d0368f

LU-5954 IOC_MDC_GETFILEINFO returns the wrong ino

req_capsule_server_get() through  __req_capsule_get in ll_dir_ioctl()
returns a pointer to a PTLRPC request or reply buffer, which is assigned
to struct mdt_body.

If the command is IOC_MDS_GETFILEINFO then the inode "st.st_ino" should
be assigned from one extracted from mdt_body through cl_fid_build_ino().
