lib: parser: update documentation for match_NUMBER functions

2023-03-03T05:54:22+00:00

commit 67222c4ba8af ("lib: parser: optimize match_NUMBER apis to use local array") removed -ENOMEM as a possible return value, so update the comments accordingly. Link: https://lkml.kernel.org/r/20230224042618.9092-1-ebiggers@kernel.org Fixes: 67222c4ba8af ("lib: parser: optimize match_NUMBER apis to use local array") Signed-off-by: Eric Biggers Cc: Li Lingfeng Cc: Tejun Heo Cc: Yu Kuai Signed-off-by: Andrew Morton

lib: parser: optimize match_NUMBER apis to use local array

2023-02-09T23:56:51+00:00

Memory will be allocated to store substring_t in match_strdup(), which means the caller of match_strdup() may need to be scheduled out to wait for reclaiming memory. smatch complains that this can cuase sleeping in an atoic context. Using local array to store substring_t to remove the restriction.

kernel.h: split out kstrtox() and simple_strtox() to a separate header

2021-07-01T18:06:05+00:00

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 kstrtox() and simple_strtox() helpers. At the same time convert users in header and lib folders to use new header. Though for time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

lib: parser: clean up kernel-doc

2021-05-07T02:24:12+00:00

Mark match_uint() as kernel-doc notation since it is already fully annotated as such. Use % prefix on constants in kernel-doc comments. Convert function return descriptions to use the "Return:" kernel-doc notation.
