Since the d_off in the first dirent for "." (that originates from the 4th argument "offset" of filldir() for the 2nd dirent for "..") is wrongly assigned in btrfs_real_readdir(), telldir returns same offset for different locations. | # mkfs.btrfs /dev/sdb1 | # mount /dev/sdb1 fs0...

...roperly so long as overflow does not occur. Thanks to your suggestion on looking at the 'xfs_growfs -n' output I think that I have finally tracked down the problem with the missing file. In IRIX systems that have version 1 naming the last entry in that directory listing has a dirent->d_off value of -1 if you treat it as a long. On systems with version 2 naming the value is not set to -1. In samba 3.0.11 there was no apparent test of the dirent->d_off field, but in 3.0.12 it performs a telldir after reading the last name and returns NULL if the offset it -1. My understanding is...

...after enough creates (and deletes :)) in a directory we end up with an entry item whose key is past that value. f_pos gets rewound instead of being set to that magical EOF. readdir() gets stuck returning the entries after INT_MAX over and over (just one in this strace): getdents(3, {{d_ino=257, d_off=2147483647, d_reclen=32, d_name="file-54"}}, 32768) = 32 getdents(3, {{d_ino=257, d_off=2147483647, d_reclen=32, d_name="file-54"}}, 32768) = 32 It took around 10 hours on a workstationy box over here to reproduce this with createmany.c from the lustre tests ("./createmany...

Hi, below comes a new version of the series of patches implementing quota support for ocfs2-tools. I've fixed the calls of ocfs2_malloc_blocks() which were given number of bytes instead of number of blocks. Besides that the series should be the same. Honza

Hi, I'm sending a series of patches implementing quota support into ocfs2-tools. It's the same as the original huge patch I've sent but now it's split as Joel asked. I've also realized that when disabling SPARSE feature, we should update quota information. That piece of code is missing, I'll implement it soon. Comments welcome. Honza

Hi, this is the next version of quota support for quota tools. I've addressed all the comments of Tao, Joel and others. Sparse feature disabling also correctly updates quota information now and the patch is merged into the tunefs support patch. Honza
