| * | [JFFS2] fix race condition in jffs2_lzo_compress() | Geert Uytterhoeven | 2008-11-05 | 1 | -6/+9 |
| | | | | | | | | | | | | | | | | deflate_mutex protects the globals lzo_mem and lzo_compress_buf. However, jffs2_lzo_compress() unlocks deflate_mutex _before_ it has copied out the compressed data from lzo_compress_buf. Correct this by moving the mutex unlock after the copy. In addition, document what deflate_mutex actually protects.

| * | [JFFS2] Add LZO compression support. | Richard Purdie | 2007-07-11 | 1 | -0/+108 |
| Add LZO1X compression/decompression support to jffs2. LZO's interface doesn't entirely match that required by jffs2 so a buffer and memcpy is unavoidable. Signed-off-by: Richard Purdie <rpurdie@openedhand.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org> | |||||
