Hi, I'm trying to read a block from disk by block_nr using __bread before the block has even been written to disk. The problem in doing this is the block is cached (junk data) and future sb_bread's return the buffer head from this cache, and not one that represent the actual data after this data has been written to disk. 1. block contains junk 2. bread -> cached junk 3. actual data written to disk through the address space object hosted by some other inode 4. bread -> still returns bh with junk Is there any way to force a read from disk while doing the second bread, or to instruct the kernel that the block that's in the cache has to be re-read?
