* fs: cleanup slight list_entry abuseRasmus Villemoes2015-06-231-1/+1
| | | | | | | | | list_entry is just a wrapper for container_of, but it is arguably wrong (and slightly confusing) to use it when the pointed-to struct member is not a struct list_head. Use container_of directly instead. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* udf: add extent cache support in case of file readingNamjae Jeon2013-01-221-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements extent caching in case of file reading. While reading a file, currently, UDF reads metadata serially which takes a lot of time depending on the number of extents present in the file. Caching last accessd extent improves metadata read time. Instead of reading file metadata from start, now we read from the cached extent. This patch considerably improves the time spent by CPU in kernel mode. For example, while reading a 10.9 GB file using dd: Time before applying patch: 11677022208 bytes (10.9GB) copied, 1529.748921 seconds, 7.3MB/s real 25m 29.85s user 0m 12.41s sys 15m 34.75s Time after applying patch: 11677022208 bytes (10.9GB) copied, 1469.338231 seconds, 7.6MB/s real 24m 29.44s user 0m 15.73s sys 3m 27.61s [JK: Fix bh refcounting issues, simplify initialization] Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com> Signed-off-by: Ashish Sangwan <a.sangwan@samsung.com> Signed-off-by: Bonggil Bak <bgbak@samsung.com> Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Init/maintain file entry checkpoint fieldSteve Nickel2012-02-291-0/+1
| | | | | | | | In accordance with ECMA 1.67 Part 4, 14.9.15, the checkpoint field should be initialized to 1 at creation. (Zero is *not* a valid value.) Signed-off-by: Steven P. Nickel <snickel@focusinfo.com> Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Replace bkl with the UDF_I(inode)->i_data_sem for protect ↵Alessio Igor Bogani2011-01-061-0/+13
| | | | | | | | | | | | | | | udf_inode_info struct Replace bkl with the UDF_I(inode)->i_data_sem rw semaphore in udf_release_file(), udf_symlink(), udf_symlink_filler(), udf_get_block(), udf_block_map(), and udf_setattr(). The rule now is that any operation on regular file's or symlink's extents (or generally allocation information including goal block) needs to hold i_data_sem. This work was supported by a hardware donation from the CE Linux Forum. Signed-off-by: Alessio Igor Bogani <abogani@texware.it> Signed-off-by: Jan Kara <jack@suse.cz>

* udf: move headers out include/linux/Christoph Hellwig2008-04-171-4/+26
| | | | | | | | | | | | | | | | 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>

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!
