* UBIFS: fix sparse warningsArtem Bityutskiy2008-12-31
| | | | | | | | | | | | | | fs/ubifs/compress.c:111:8: warning: incorrect type in argument 5 (different signedness) fs/ubifs/compress.c:111:8: expected unsigned int *dlen fs/ubifs/compress.c:111:8: got int *out_len fs/ubifs/compress.c:175:10: warning: incorrect type in argument 5 (different signedness) fs/ubifs/compress.c:175:10: expected unsigned int *dlen fs/ubifs/compress.c:175:10: got int *out_len Fix this by adding a cast to (unsigned int *). We guarantee that our lengths are small and no overflow is possible. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBIFS: introduce compression mount optionsArtem Bityutskiy2008-12-03
| | | | | | | | It is very handy to be able to change default UBIFS compressor via mount options. Introduce -o compr=<name> mount option support. Currently only "none", "lzo" and "zlib" compressors are supported. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: slight compression optimizationArtem Bityutskiy2008-12-03
| | | | | | | | If data does not compress, it is better to leave it uncompressed because we'll read it faster then. So do not compress data if we save less than 64 bytes. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
