* udf: Convert UDF to new truncate calling sequenceJan Kara2011-02-231-7/+5
| | | | | | | Use new truncation sequence in UDF and fix up error handling in the code. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Move handling of uniqueID into a helper function and protect it by a ↵Jan Kara2011-01-061-0/+1
| | | | | | | | | | s_alloc_mutex uniqueID handling has been duplicated in three places. Move it into a common helper. Since we modify an LVID buffer with uniqueID update, we take sbi->s_alloc_mutex to protect agaist other modifications of the structure. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Remove BKL from udf_update_inodeJan Kara2011-01-061-1/+0
| | | | | | | | | | | udf_update_inode() does not need BKL since on-disk inode modifications are protected by the buffer lock and reading of values of in-memory inode is safe without any lock. In some cases we can write inconsistent inode state to disk but in that case inode will be marked dirty and overwritten later. Also make unnecessarily global udf_sync_inode() static.

* udf: Remove dead quota codeJan Kara2010-05-241-1/+0
| | | | | | | | | | Quota on UDF is non-functional at least since 2.6.16 (I'm too lazy to do more archeology) because it does not provide .quota_write and .quota_read functions and thus quotaon(8) just returns EINVAL. Since nobody complained for all those years and quota support is not even in UDF standard just nuke it. Signed-off-by: Jan Kara <jack@suse.cz>

* pass writeback_control to ->write_inodeChristoph Hellwig2010-03-051-1/+1
| | | | | | | | | | This gives the filesystem more information about the writeback that is happening. Trond requested this for the NFS unstable write handling, and other filesystems might benefit from this too by beeing able to distinguish between the different callers in more detail.

* udf: Don't write integrity descriptor too oftenJan Kara2009-04-021-0/+11
| | | | | | | | | | | | | | | | We update information in logical volume integrity descriptor after each allocation (as LVID contains free space, number of directories and files on disk etc.). If the filesystem is on some phase change media, this leads to its quick degradation as such media is able to handle only 10000 overwrites or so. We solve the problem by writing new information into LVID only on umount, remount-ro and sync. This solves the problem at the price of longer media inconsistency (previously media became consistent after pdflush flushed dirty LVID buffer) but that should be acceptable.

Error resilience is implemented through accessing the Metadata Mirror File in case the data the Metadata File cannot be read.

* udf: move headers out include/linux/Christoph Hellwig2008-04-171-3/+22
| | | | | | | | | | | | | | | | There's really no reason to keep udf headers in include/linux as they're not used by anything but fs/udf/. This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h, include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and include/linux/udf_fs.h into fs/udf/udfdecl.h. The only thing remaining in include/linux/ is a stub of udf_fs_i.h defining the four user-visible udf ioctls. It's also moved from unifdef-y to headers-y because it can be included unconditionally now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>

* udf: fix possible leakage of blocksJan Kara2007-06-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | We have to take care that when we call udf_discard_prealloc() from udf_clear_inode() we have to write inode ourselves afterwards (otherwise, some changes might be lost leading to leakage of blocks, use of free blocks or improperly aligned extents). Also udf_discard_prealloc() does two different things - it removes preallocated blocks and truncates the last extent to exactly match i_size. We move the latter functionality to udf_truncate_tail_extent(), call udf_discard_prealloc() when last reference to a file is dropped and call udf_truncate_tail_extent() when inode is being removed from inode cache (udf_clear_inode() call). We cannot call udf_truncate_tail_extent() earlier as subsequent open+write would find the last block of the file mapped and happily write to the end of it, although the last extent says it's shorter.

* [PATCH] mark struct inode_operations const 3Arjan van de Ven2007-02-121-2/+2
| | | | | | | | | | | Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+167
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
