* scsi: ilog2: create truly constant version for sparseMartin Wilck2018-08-241-11/+24
| | | | | | | | | | | | | | | | | | Sparse emits errors about ilog2() in array indices because of the use of __ilog2_32() and __ilog2_64(), rightly so (https://www.spinics.net/lists/linux-sparse/msg03471.html). Create a const_ilog2() variant that works with sparse for this scenario. (Note: checkpatch.pl complains about missing parentheses, but that appears to be a false positive. I can get rid of the warning simply by inserting whitespace, making checkpatch "see" the whole macro). Signed-off-by: Martin Wilck <mwilck@suse.com> Signed-off-by: Martin K.

* give up on gcc ilog2() constant optimizationsLinus Torvalds2018-08-241-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc-7 has an "optimization" pass that completely screws up, and generates the code expansion for the (impossible) case of calling ilog2() with a zero constant, even when the code gcc compiles does not actually have a zero constant. And we try to generate a compile-time error for anybody doing ilog2() on a constant where that doesn't make sense (be it zero or negative). So now gcc7 will fail the build due to our sanity checking, because it created that constant-zero case that didn't actually exist in the source code. There's a whole long discussion on the kernel mailing about how to work around this gcc bug. The gcc people themselevs have discussed their "feature" in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72785 but it's all water under the bridge, because while it looked at one point like it would be solved by the time gcc7 was released, that was not to be. So now we have to deal with this compiler braindamage. And the only simple approach seems to be to just delete the code that tries to warn about bad uses of ilog2(). So now "ilog2()" will just return 0 not just for the value 1, but for any non-positive value too. It's not like I can recall anybody having ever actually tried to use this function on any invalid value, but maybe the sanity check just meant that such code never made it out in public.

* log2: make order_base_2() behave correctly on const input value zeroArd Biesheuvel2018-08-241-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The function order_base_2() is defined (according to the comment block) as returning zero on input zero, but subsequently passes the input into roundup_pow_of_two(), which is explicitly undefined for input zero. This has gone unnoticed until now, but optimization passes in GCC 7 may produce constant folded function instances where a constant value of zero is passed into order_base_2(), resulting in link errors against the deliberately undefined '____ilog2_NaN'. So update order_base_2() to adhere to its own documented interface. [ See http://marc.info/?l=linux-kernel&m=147672952517795&w=2 and follow-up discussion for more background. The gcc "optimization pass" is really just broken, but now the GCC trunk problem seems to have escaped out of just specially built daily images, so we need to work around it in mainline. - Linus ] Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> [andrew.smirnov@gmail.com: Applied kernel patch to Barebox as-is] Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* / fs: dentry cache implementationSascha Hauer2018-07-115-41/+256
|/ | | | | | | | | | | | | | | | | | | | | | | This adds the Linux dentry cache implementation to barebox. Until now every filesystem driver resolves the full path to a file for itself. This leads to code duplication and is error prone since resolving paths is a complicated task. Also it can narrow down the lookup performance since barebox only knows ASCII paths and has no way of caching lookups. With this patch we get the Linux dcache implementation. The path resolving code from fs/namei.c is nearly taken as-is, minus the RCU and locking code. Dcaching is made simple as of now: We simply cache everything and never release any dentries. Although we do reference counting for inodes and dentries it is effectively not used yet. We never free anything until a fs is unmounted in which case we free everything no matter if references are taken or not. This patch also contains a wrapper in fs/legacy.c to support filesystems with the old API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
