This is done by waiting on bit CIFS_INODE_PENDING_OPLOCK_BREAK in cifsFileInfo->flags. This bit is cleared by the oplock break handler job queued on the workqueue once it has completed handling the oplock break allowing writers to proceed with writing to the file. While testing, it was noticed that the filehandle could be closed while there is a pending oplock break which results in the oplock break handler on the cifsiod workqueue being cancelled before it has had a chance to execute and clear the CIFS_INODE_PENDING_OPLOCK_BREAK bit. Any subsequent attempt to write to this file hangs waiting for the CIFS_INODE_PENDING_OPLOCK_BREAK bit to be cleared. We fix this by ensuring that we also clear the bit CIFS_INODE_PENDING_OPLOCK_BREAK when we remove the oplock break handler from the workqueue. The bug was found by Red Hat QA while testing using ltp's fsstress command.

Running chown with strace tells me that each directory has the same device and inode number: newfstatat(AT_FDCWD, "/nfs/", {st_dev=makedev(0, 38), st_ino=2, ...}) = 0 newfstatat(4, "vol1", {st_dev=makedev(0, 38), st_ino=2, ...}) = 0 newfstatat(4, "vol2", {st_dev=makedev(0, 38), st_ino=2, ...}) = 0 With this patch the mounted_on_fileid values are used for st_ino, so the directory loop warning isn't reported.

However VFS quotas track usage in bytes (as some filesystems require that) and we need to somehow pass this information. Upto now it wasn't a problem because we didn't do any unit conversion (thus VFS quota routines happily stuck number of bytes into d_bcount field of struct fd_disk_quota). Only if you tried to use Q_XGETQUOTA or Q_XSETQLIM for VFS quotas (or Q_GETQUOTA / Q_SETQUOTA for XFS quotas), you got bogus results. Hardly anyone tried this but reportedly some Samba users hit the problem in practice. So when we want interfaces compatible we need to fix this. We bite the bullet and define another quota structure used for passing information from/to ->get_dqblk()/->set_dqblk. It's somewhat sad we have to have more conversion routines in fs/quota/quota.c and another copying of quota structure slows down getting of quota information by about 2% but it seems cleaner than overloading e.g. units of d_bcount to bytes.
