Subject: pNFS/files: filelayout_write_done_cb must call nfs_writeback_update_inode()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e033fb51ebb2983ee17b4a1b96ccbaedb137d9e9;p=openwrt%2Fstaging%2Fblogic.git

pNFS/files: filelayout_write_done_cb must call nfs_writeback_update_inode()

All write callbacks are required to call nfs_writeback_update_inode() upon
success to ensure that file size changes are recorded, and the attribute
cache is invalidated.
