[XFS] avoid memory allocations in xfs_fs_vcmn_err

2008-12-22T07:02:01+00:00

xfs_fs_vcmn_err can be called under a spinlock, but does a sleeping memory
allocation to create buffer for it's internal sprintf.  Fortunately it's
the only caller of icmn_err, so we can merge the two and have one single
static buffer and spinlock protecting it.  While we're at it make sure
we proper __attribute__ format annotations so that the compiler can detect
mismatched format strings.

[XFS] kill INDUCE_IO_ERROR

2008-08-13T06:17:37+00:00

All the error injection is already enabled through ifdef DEBUG, so kill
the never set second cpp symbol to activate it without the rest of the
debugging infrastructure.

[XFS] streamline init/exit path

2008-07-28T06:59:25+00:00

Currently the xfs module init/exit code is a mess. It's farmed out over a
lot of function with very little error checking. This patch makes sure we
propagate all initialization failures properly and clean up after them.
Various runtime initializations are replaced with compile-time
initializations where possible to make this easier. The exit path is
similarly consolidated.

There's now split out function to create/destroy the kmem zones and
alloc/free the trace buffers. I've also changed the ktrace allocations to
KM_MAYFAIL and handled errors resulting from that.

And yes, we really should replace the XFS_*_TRACE ifdefs with a single
XFS_TRACE..

[XFS] lose xfs_hex_dump in favor of print_hex_dump

2008-02-07T07:13:05+00:00

No need for xfs to have its own hex dumping routine now that the kernel
has one.

[XFS] kill the vfs_fsid and vfs_altfsid members in struct bhv_vfs

2007-10-16T01:45:02+00:00

vfs_altfsid was just a pointer to mp->m_fixedfsid so we can trivially
replace it with the latter. vfs_fsid also was identical to m_fixedfsid
through rather obfuscated ways so we can kill it as well and simply its
only user.

[XFS] Make quiet mounts quiet

2007-02-10T07:27:56+00:00

The XFS quiet mount logic was inverted making quiet mounts noisy and vice
versa. Fix it.
