* kbuild: remove hardcoded _logo names from modpostSam Ravnborg2007-07-162-16/+5
| | | | | | | | | | Replaced this with a __init_refok marker in front of fb_find_logo(). I think that the __initdata marker for the logo's are wrong but I have not justified this so I did not remove it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: remove hardcoded apic_es7000 from modpostSam Ravnborg2007-07-162-2/+1

* kbuild: warn about references from .init.text to .exit.textSam Ravnborg2007-07-161-1/+0
| | | | | | | The .exit.text section may be discarded either at build or at runtime. So let modpost warn if this situation is detected. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: consolidate section checksSam Ravnborg2007-07-161-25/+7
| | | | | | | | | Move more checks from whitelist to the section check functions. Remove the redundent pci_fixup check. Renumber the patterns. No functional changes. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: refactor code in modpost to improve maintainabilitySam Ravnborg2007-07-161-79/+75
| | | | | | | | | There were a great deal of overlap between the two functions that check which sections may reference .init.text and .exit.text. Factor out common check to a separate function and sort entries in the original functions. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: ignore section mismatch warnings originating from .note sectionSam Ravnborg2007-07-161-0/+2
| | | | | | | | | | | .note* sections are ELF notes, which are typically used by external tools to examine the kernel image. Since this is removed from any runtime consideration, it's OK to reference any section from a .note* section. Signed-off-by: Jeremy Fitzhardinge <jeremy@xensource.com> Cc: "Eric W.

* kbuild: make better section mismatch reports on i386 and mipsAtsushi Nemoto2007-07-162-0/+76
| | | | | | | | | | On i386 and MIPS, warn_sec_mismatch() sometimes fails to show usefull symbol name. This is because empty 'refsym' due to 0 r_addend value. This patch is to adjust r_addend value, consulting with apply_relocate() routine in kernel code. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kconfig: fix update-po-configSam Ravnborg2007-07-162-18/+21
| | | | | | | | | | | | | | | | | | | | | | | Massimo Maiurana <maiurana@gmail.com> reported that update-po-config was broken: 1) spelling errors in Makefile so arch/um failed 2) UTF-8 was not supported The following patch address the above problems. kxgettext now append the output to the .pot file generated by xgettext - so we have a header. In all places UFT-8 is specifed so we now flawlessly support UTF-8. The Kconfig files had an empty string in a few cases - these are now supressed in kxgettext. With this the translators can now pick up where they left and get it all translated. There are ~11000 strings to be translated...

* kbuild: add support for squashing uid/gid in gen_initramfs_list.shMike Frysinger2007-07-161-6/+6
| | | | | | | | | | | Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of current owner. For example, in build systems that get run as arbitrary users (uClinux-dist). This adds a special "squash" keyword so you can do '-g squash -u squash' and have ownership squashed to root.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to allocate and deallocate regions to a file without zeroing data or changing i_size. Though renamed, the structure passed in from user is identical to struct xfs_flock64. The three fields that are actually used right now are l_whence, l_start and l_len. This should get ocfs2 immediate compatibility with userspace software using the pre-existing xfs ioctls. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide an internal interface for the removal of arbitrary file regions. ocfs2_remove_inode_range() takes a byte range within a file and will remove existing extents within that range. Partial clusters will be zeroed so that any read from within the region will return zeros. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * | ocfs2: update truncate handling of partial clustersMark Fasheh2007-07-103-46/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | The partial cluster zeroing code used during truncate usually assumes that the rightmost byte in the range to be zeroed lies on a cluster boundary. This makes sense for truncate, but punching holes might require zeroing on non-aligned rightmost boundaries. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Add code to the btree paths to support the removal of arbitrary regions within an existing extent. With proper higher level support this can be used to "punch holes" in a file. Truncate (a special case of hole punching) could also be converted to use these methods.

| * | ocfs2: Support creation of unwritten extentsMark Fasheh2007-07-107-28/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can now be trivially supported with re-use of our existing extend code. ocfs2_allocate_unwritten_extents() takes a start offset and a byte length and iterates over the inode, adding extents (marked as unwritten) until len is reached. Existing extents are skipped over. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * | ocfs2: support writing of unwritten extentsMark Fasheh2007-07-103-26/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the write code to detect when the user is asking to write to an unwritten extent. Like writing to a hole, we must zero the region between the write and the cluster boundaries. Most of the existing cluster zeroing logic can be re-used with some additional checks for the unwritten flag on extent records. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Writes to a region marked as unwritten might result in a record split or merge. We can support splits by making minor changes to the existing insert code. Merges require left rotations which mostly re-use right rotation support functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The top level calls and logic for growing a tree can easily be abstracted out of ocfs2_insert_extent() into a seperate function - ocfs2_grow_tree().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Deallocation of suballocator blocks, most notably extent blocks, might involve multiple suballocator inodes. The locking for this can get extremely complicated, especially when the suballocator inodes to delete from aren't known until deep within an unrelated codepath. Implement a simple scheme for recording the blocks to be unlinked so that the actual deallocation can be done in a context which won't deadlock. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * | ocfs2: harden buffer check during mapping of page blocksMark Fasheh2007-07-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | We don't want to submit buffer_new blocks for read i/o. This actually won't happen right now because those requests during an allocating write are all nicely aligned. It's probably a good idea to provide an explicit check though.

The code now understands multiple cluster writes as a result of having to deal with a full page write for greater than 4k pages.
