From 2c6292ae4be00454882246d07f38cdf15a823c2a Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 17 Jun 2011 09:05:48 -0400 Subject: cifs: don't pass superblock to cifs_mount() To close sget() races we'll need to be able to set cifs_sb up before we get the superblock, so we'll want to be able to do cifs_mount() earlier. Fortunately, it's easy to do - setting ->s_maxbytes can be done in cifs_read_super(), ditto for ->s_time_gran and as for putting MS_POSIXACL into ->s_flags, we can mirror it in ->mnt_cifs_flags until cifs_read_super() is called. Kill unused 'devname' argument, while we are at it...
