Message-ID: <AANLkTi=hcR-Kt32PNt7pbmTo0Jaco9QPvfOZQ8BpyKaZ@mail.gmail.com> Date: Wed, 23 Mar 2011 18:30:13 +0800 From: real mz <realmz6@...il.com> To: sfrench@...ibm.com, linux-cifs@...r.kernel.org, linux-kernel@...r.kernel.org, uclinux-dist-devel@...ckfin.uclinux.org Subject: cifs: read dir issue on no-mmu platform Hi Guys, I've got a read dir error on no-mmu platform. After mount cifs to /mnt, enter /mnt, mkdir aa then enter aa, mkdir bb, it said "File exists", but actually it's a empty dir. This issue will never happen on arm platform, is there any clues to debug it? //10.99.29.111/temp on /mnt type cifs (rw,mand,relatime,unc=\\10.99.29.111\temp,username=steven,uid=0,noforceuid,gid=0,noforcegid,addr=10.99.29.111,posixpaths,acl,rsize=16384,wsize=57344,actimeo=1) root:/mnt> ls bt_settings.tar.gz doc root:/mnt> mkdir aa root:/mnt> cd aa/ root:/mnt/aa> ls root:/mnt/aa> mkdir bb mkdir: can't create directory 'bb': File exists root:/mnt/aa> cat /proc/fs/cifs/DebugData Display Internal CIFS Data Structures for Debugging --------------------------------------------------- CIFS Version 1.71 Features: lanman posix xattr acl Active VFS Requests: 0 Servers: 1) Name: 10.99.29.111 Domain: WORKGROUP Uses: 1 OS: Unix NOS: Samba 3.2.5 Capability: 0x80f3fd SMB session status: 1 TCP status: 1 Local Users To Server: 1 SecMode: 0x2 Req On Wire: 0 Shares: 1) \\10.99.29.111\temp Mounts: 1 Type: NTFS DevInfo: 0x0 Attributes: 0x1002f PathComponentMax: 255 Status: 0x1 type: 0 MIDs: I enabled the cifsFYI and get the following trace logs: fs/cifs/inode.c: CIFS VFS: in cifs_revalidate_dentry as Xid: 58725 with uid: 0 fs/cifs/inode.c: Revalidate: inode 0x02c27dec count 1 dentry: 0x029b22b4 d_time 0 jiffies 965567 fs/cifs/inode.c: Getting info on fs/cifs/cifssmb.c: In QPathInfo (Unix) the path fs/cifs/transport.c: For smb_command 50 fs/cifs/transport.c: Sending smb: total_len 78 fs/cifs/connect.c: rfc1002 length 0xa4 fs/cifs/transport.c: sync_mid_result: cmd=50 mid=1163 state=4 fs/cifs/inode.c: cifs_revalidate_cache: revalidating inode 4549328 fs/cifs/inode.c: cifs_revalidate_cache: inode 4549328 is unchanged fs/cifs/inode.c: inode 0x02c27dec old_time=962297 new_time=965567 fs/cifs/inode.c: CIFS VFS: leaving cifs_revalidate_dentry (xid = 58725) rc = 0 fs/cifs/inode.c: CIFS VFS: in cifs_revalidate_dentry as Xid: 58726 with uid: 0 fs/cifs/inode.c: CIFS VFS: leaving cifs_revalidate_dentry (xid = 58726) rc = 0 fs/cifs/readdir.c: CIFS VFS: in cifs_readdir as Xid: 58727 with uid: 0 fs/cifs/readdir.c: Full path: start at: 0 fs/cifs/cifssmb.c: In FindFirst for fs/cifs/transport.c: For smb_command 50 fs/cifs/transport.c: Sending smb: total_len 88 fs/cifs/connect.c: rfc1002 length 0x234 fs/cifs/transport.c: sync_mid_result: cmd=50 mid=1164 state=4 fs/cifs/readdir.c: initiate cifs search rc 0 fs/cifs/readdir.c: end of search fs/cifs/readdir.c: found entry -
