And that is a typecast to _Bool now, which (mostly) takes just a byte. Anyway, the bool type is implementation defined, and better we don't assume its size to be 4 bytes or 1. The problem with current code is that it reads/writes 4 bytes for a boolean, which will read/update 3 excess bytes following the boolean variable (when sizeof(bool) is 1 byte). And that can lead to hard to fix bugs. It was a nightmare cracking this one. The debugfs code had this bug since the first time it got introduced, but was never got caught, strange. Maybe the bool variables (monitored by debugfs) were followed by an 'int' or something bigger and the pad bytes made sure, we never see this issue. But the OPP (Operating performance points) library have three booleans allocated to contiguous bytes and this bug got hit quite soon (The debugfs support for OPP is yet to be merged). It showed up as corruption of the debugfs boolean symbols, where Y were becoming N and vice versa. Fix it properly by changing the last argument of debugfs_create_bool(), to type 'bool *' instead of 'u32 *', so that it doesn't depend on sizeof bool at all. That required updates to all user sites as well in a single commit. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well. Acked-by: Mark Brown Signed-off-by: Viresh Kumar --- V2->V3: - Moved a bug fix in a separate patch 1/2, so that it can be backported. - Added Ack from Mark.
