Currently orphan cleanup only ever gets triggered if we cross subvolumes during a lookup, which means that if we just mount a plain jane fs that has orphans in it, they will never get cleaned up. This results in panic's like these http://www.kerneloops.org/oops.php?number=1109085 where adding an orphan entry results in -EEXIST being returned and we panic. In order to fix this, we check to see on lookup if our root has had the orphan cleanup done, and if not go ahead and do it. This is easily reproduceable by running this testcase #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <string.h> #include <unistd.h> #include <stdio.h> int main(int argc, char **argv) { char data[4096]; char newdata[4096]; int fd1, fd2; memset(data, 'a', 4096); memset(newdata, 'b', 4096); while (1) { int i; fd1 = creat("file1", 0666); if (fd1 < 0) break; for (i = 0; i < 512; i++) write(fd1, data, 4096); fsync(fd1); close(fd1); fd2 = creat("file2", 0666); if (fd2 < 0) break; ftruncate(fd2, 4096 * 512); for (i = 0; i < 512; i++) write(fd2, newdata, 4096); close(fd2); i = rename("file2", "file1"); unlink("file1"); } return 0; } and then pulling the power on the box, and then trying to run that test again when the box comes back up. I've tested this locally and it fixes the problem. Thanks to Tomas Carnecky for helping me track this down initially.

Fix bug reported by Johannes Hirte. The reason of that bug is btrfs_del_items is called after btrfs_duplicate_item and btrfs_del_items triggers tree balance.

parent 49313cdac7b34c9f7ecbb1780cfc648b1c082cd7 (v2.6.32-1-g49313cd) commit ff48c08e1c05c67e8348ab6f8a24de8034e0e34d Author: Jan Engelhardt <jengelh@medozas.de> Date: Wed Dec 9 22:57:36 2009 +0100 Btrfs: fix missing last-entry in readdir(3) When one does a 32-bit readdir(3), the last entry of a directory is missing. This is however not due to passing a large value to filldir, but it seems to have to do with glibc doing telldir or something quirky. In any case, this patch fixes it in practice.

This patch makes us a bit less zealous about making sure we have enough free metadata space by pearing down the size of new metadata chunks to 256mb instead of 1gb. Also, we used to try an allocate metadata chunks when allocating data, but that sort of thing is done elsewhere now so we can just remove it. With my -ENOSPC test I used to have 3gb reserved for metadata out of 75gb, now I have 1.7gb.

On the parisc architecture we face for each and every loaded kernel module this kernel "badness warning": sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text' Badness at fs/sysfs/dir.c:487 Reason for that is, that on parisc all kernel modules do have multiple .text sections due to the usage of the -ffunction-sections compiler flag which is needed to reach all jump targets on this platform. An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ... Since the .text sections are empty (size of 0 bytes) and won't be loaded by the kernel module loader anyway, I don't see a reason why such sections need to be listed under /sys/module/<module_name>/sections/<section_name> either. The attached patch does solve this issue by not exporting section names which are empty.
