[XFS] fix 32-bit compat ioctls for GETXFLAGS, SETXFLAGS, GETVERSION · bc58f9bb

由 Eric Sandeen 提交于 10月 12, 2007

XFS_IOC_GETVERSION, XFS_IOC_GETXFLAGS and XFS_IOC_SETXFLAGS all take a
"long" which changes size between 32 and 64 bit platforms.

So, the ioctl cmds that come in from a 32-bit app aren't as expected, for
example on GETXFLAGS,

unknown cmd fd(3) cmd(80046601){t:'f';sz:4}

due to the size mismatch.

So, use instead the 32-bit version of the commands for compat ioctls, and
other than that it doesn't take any more manipulation.

Also, for both native and compat versions, just define them to the values
as defined in fs.h

[XFS] kill superflous buffer locking · c40ea741

由 Christoph Hellwig 提交于 10月 12, 2007

There is no need to lock any page in xfs_buf.c because we operate on our
own address_space and all locking is covered by the buffer semaphore. If
we ever switch back to main blockdeive address_space as suggested e.g. for
fsblock with a similar scheme the locking will have to be totally revised
anyway because the current scheme is neither correct nor coherent with
itself.

[XFS] Refactor xfs_mountfs · 0771fb45

由 Eric Sandeen 提交于 10月 12, 2007

Refactoring xfs_mountfs() to call sub-functions for logical chunks can
help save a bit of stack, and can make it easier to read this long
function.

The mount path is one of the longest common callchains, easily getting to
within a few bytes of the end of a 4k stack when over lvm, quotas are
enabled, and quotacheck must be done.

With this change on top of the other stack-related changes I've sent, I
can get xfs to survive a normal xfsqa run on 4k stacks over lvm.

[XFS] xlog_rec_header/xlog_rec_ext_header endianess annotations · b53e675d

由 Christoph Hellwig 提交于 10月 12, 2007

Mostly trivial conversion with one exceptions: h_num_logops was kept in
native endian previously and only converted to big endian in xlog_sync,
but we always keep it big endian now. With todays cpus fast byteswap
instructions that's not an issue but the new variant keeps the code clean
and maintainable.

[XFS] clean up some xfs_log_priv.h macros · 67fcb7bf

由 Christoph Hellwig 提交于 10月 12, 2007

- the various assign lsn macros are replaced by a single inline,
xlog_assign_lsn, which is equivalent to ASSIGN_ANY_LSN_HOST except
for a more sane calling convention. ASSIGN_LSN_DISK is replaced
by xlog_assign_lsn and a manual bytespap, and ASSIGN_LSN by the same,
except we pass the cycle and block arguments explicitly instead of a
log paramter. The latter two variants only had 2, respectively one
user anyway.
- the GET_CYCLE is replaced by a xlog_get_cycle inline with exactly the
same calling conventions.
- GET_CLIENT_ID is replaced by xlog_get_client_id which leaves away
the unused arch argument. Instead of conditional defintions
depending on host endianess we now do an unconditional swap and shift
then, which generates equal code.
- the unused XLOG_SET macro is removed.

[XFS] Kill off xfs_statvfs. · 4ca488eb

由 Christoph Hellwig 提交于 10月 11, 2007

We were already filling the Linux struct statfs anyway, and doing this
trivial task directly in xfs_fs_statfs makes the code quite a bit cleaner.
While I was at it I also moved copying attributes that don't change over
the lifetime of the filesystem outside the superblock lock.

xfs_fs_fill_super used to get the magic number and blocksize through
xfs_statvfs, but assigning them directly is a lot cleaner and will save
some stack space during mount.

[XFS] kill xfs_iocore_t · 613d7043

xfs_iocore_t is a structure embedded in xfs_inode. Except for one field it
just duplicates fields already in xfs_inode, and there is nothing this
abstraction buys us on XFS/Linux. This patch removes it and shrinks source
and binary size of xfs aswell as shrinking the size of xfs_inode by 60/44
bytes in debug/non-debug builds.
