VFS: factor out three helpers for FIBMAP/FIONBIO/FIOASYNC file ioctls

2008-02-07T16:42:16+00:00

Factor out file-specific ioctl code into smaller helper functions, away from
file_ioctl().  This helps code readability and also reduces indentation inside
case statements.

VFS: swap do_ioctl and vfs_ioctl names

2008-02-07T16:42:16+00:00

Rename old vfs_ioctl to do_ioctl, because the comment above it clearly
indicates that it is an internal function not to be exported to modules;
therefore it should have a more traditional do_XXX name.  The new do_ioctl
is exported in fs.h but not to modules.

Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should
preferably be reserved to callable VFS functions which modules may call, as
many other vfs_XXX functions already do.  Export the new vfs_ioctl to GPL
modules so others can use it (including Unionfs and eCryptfs).  Add DocBook
for new vfs_ioctl.

drop obsolete sys_ioctl export

2007-07-16T16:05:48+00:00

sys_ioctl() was only exported for our first version of compat ioctl
handling.  Now that the whole compat ioctl handling mess is more or less
sorted out there are no more modular users left and we can kill it.

There's one exception and that's sparc64's solaris compat module, but
sparc64 has it's own export predating the generic one by years for that
which this patch leaves untouched.

vanishing ioctl handler debugging

2007-06-04T20:25:10+00:00

We've had several reoprts of the CPU jumping to 0x00000000 is do_ioctl().  I
assume that there's a race and someone is zeroing out the ioctl handler while
this CPU waits for the lock_kernel().

The patch adds code to detect this, then emits stuff which will hopefuly lead
us to the culprit.

[PATCH] VFS: change struct file to use struct path

2006-12-08T16:28:41+00:00

This patch changes struct file to use struct path instead of having
independent pointers to struct dentry and struct vfsmount, and converts all
users of f_{dentry,vfsmnt} in fs/ to use f_path.{dentry,mnt}.

Additionally, it adds two #define's to make the transition easier for users of
the f_dentry and f_vfsmnt.
