| * udf: Fix deadlock when converting file from in-ICB one to normal oneJan Kara2012-01-091-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During BKL removal in 2.6.38, conversion of files from in-ICB format to normal format got broken. We call ->writepage with i_data_sem held but udf_get_block() also acquires i_data_sem thus creating A-A deadlock. We fix the problem by dropping i_data_sem before calling ->writepage() which is safe since i_mutex still protects us against any changes in the file. Also fix pagelock - i_data_sem lock inversion in udf_expand_file_adinicb() by dropping i_data_sem before calling find_or_create_page().

| | | | | | | | | Superblock carries credentials (uid, gid, etc.) which are used as default values in __udf_read_inode() when media does not provide these.

This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the initialization. For most metadata operations this is a straight forward move into the methods, but for truncate and open it's a bit more complicated. For truncate we currently only call vfs_dq_init for the sys_truncate case because open already takes care of it for ftruncate and open(O_TRUNC) - the new code causes an additional vfs_dq_init for those which is harmless. For open the initialization is moved from do_filp_open into the open method, which means it happens slightly earlier now, and only for regular files. The latter is fine because we don't need to initialize it for operations on special files, and we already do it as part of the namespace operations for directories.

* udf: Avoid IO in udf_clear_inodeJan Kara2009-12-141-12/+12
| | | | | | | | | | | | | | | | | | | It is not very good to do IO in udf_clear_inode. First, VFS does not really expect inode to become dirty there and thus we have to write it ourselves, second, memory reclaim gets blocked waiting for IO when it does not really expect it, third, the IO pattern (e.g. on umount) resulting from writes in udf_clear_inode is bad and it slows down writing a lot. The reason why UDF needed to do IO in udf_clear_inode is that UDF standard mandates extent length to exactly match inode size. But when we allocate extents to a file or directory, we don't really know what exactly the final file size will be and thus temporarily set it to block boundary and later truncate it to exact length in udf_clear_inode. Now, this is changed to truncate to final file size in udf_release_file for regular files. For directories and symlinks, we do the truncation at the moment when learn what the final file size will be. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Perform preallocation only for regular filesJan Kara2009-09-141-9/+10
| | | | | | | | | | | | | | | | So far we preallocated blocks also for directories but that brings a problem, when to get rid of preallocated blocks we don't need. So far we removed them in udf_clear_inode() which has a disadvantage that 1) blocks are unavailable long after writing to a directory finished and thus one can get out of space unnecessarily early 2) releasing blocks from udf_clear_inode is problematic because VFS does not expect us to redirty inode there and it also slows down memory reclaim. So preallocate blocks only for regular files where we can drop preallocation in udf_release_file. Signed-off-by: Jan Kara <jack@suse.cz>

* udf: Fix BUG_ON() in destroy_inode()Jan Kara2008-11-271-0/+1
| | | | | | | | | | | udf_clear_inode() can leave behind buffers on mapping's i_private list (when we truncated preallocation). Call invalidate_inode_buffers() so that the list is properly cleaned-up before we return from udf_clear_inode(). This is ugly and suggest that we should cleanup preallocation earlier than in clear_inode() but currently there's no such call available since drop_inode() is called under inode lock and thus is unusable for disk operations.
