Kconfig allows to customize the CONFIG_ prefix via the $CONFIG_ environment variable. Out-of-tree projects may therefore use Kconfig with a different prefix, or they may use a custom configuration tool which does not use the CONFIG_ prefix at all. Such projects may still want to adhere to the Linux kernel coding style and run checkpatch.pl. One example is OP-TEE [1] which does not use Kconfig but does have configuration options prefixed with CFG_. It also mostly follows the kernel coding style and therefore being able to use checkpatch is quite valuable. To make this possible, add the --kconfig-prefix command line option.

Whether crc32_be needs a lookup table is chosen based on CRC_LE_BITS. Obviously, the _be function should be governed by the _BE_ define. This probably never pops up as it's hard to come up with a configuration where CRC_BE_BITS isn't the same as CRC_LE_BITS and as nobody is using bitwise CRC anyway.

Add a macro to test if entry is pointing to the head of the list which is useful in cases like: list_for_each_entry(pos, &head, member) { if (cond) break; } if (list_entry_is_head(pos, &head, member)) return -ERRNO; that allows to avoid additional variable to be added to track if loop has not been stopped in the middle. While here, convert list_for_each_entry*() family of macros to use a new one. Signed-off-by:

The documentation for these functions indicates that callers don't need to hold a lock while calling them, but that documentation is only in one place under "IDA Usage". Let's state the same information on each IDA function so that it's clear what the calling context requires. Furthermore, let's document ida_simple_get() with the same information so that callers know how this API works. Signed-off-by:

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out min()/max() et al. helpers. At the same time convert users in header and lib folder to use new header. Though for time being include new header back to kernel.h to avoid twisted indirected includes for other existing users.

If we fail to decompress in zram it's a pretty serious problem. We were entrusted to be able to decompress the old data but we failed. Either we've got some crazy bug in the compression code or we've got memory corruption. At the moment, when this happens the log looks like this: ERR kernel: [ 1833.099861] zram: Decompression failed! err=-22, page=336112 ERR kernel: [ 1833.099881] zram: Decompression failed! err=-22, page=336112 ALERT kernel: [ 1833.099886] Read-error on swap-device (253:0:2688896) It is true that we have an "ALERT" level log in there, but (at least to me) it feels like even this isn't enough to impart the seriousness of this error. Let's convert to a WARN_ON. Note that WARN_ON is automatically "unlikely" so we can simply replace the old annotation with the new one. Signed-off-by:
