Hi Luis,
As per your suggestion [1], this is an attempt to refactor and split
optional code out of core module support code into separate components.
This version is based on Linus' commit e6251ab4551f ("Merge tag
'nfs-for-5.17-2' of git://git.linux-nfs.org/projects/anna/linux-nfs").
Please let me know your thoughts. So far, no feedback from 0-day; albeit,
if I see something, I'll let you know.
Changes since v1 [2]:
- Moved module version support code into a new file
Changes since v2 [3]:
- Moved module decompress support to a separate file
- Made check_modinfo_livepatch() generic (Petr Mladek)
- Removed filename from each newly created file (Luis Chamberlain)
- Addressed some (i.e. --ignore=ASSIGN_IN_IF,AVOID_BUG was used)
minor scripts/checkpatch.pl concerns e.g., use strscpy over
strlcpy and missing a blank line after declarations (Allen)
Changes since v3 [4]:
- Refactored both is_livepatch_module() and set_livepatch_module(),
respectively, to use IS_ENABLED(CONFIG_LIVEPATCH) (Joe Perches)
- Addressed various compiler warnings e.g., no previous prototype (0-day)
Changes since v4 [5]:
- Dropped RFC (Luis Chamberlain)
- Moved is_livepatch_module() and set_livepatch_module() to
kernel/module/livepatch.c; set_livepatch_module() will
remain for internal use only
- Addressed minor compiler warning concerning
kernel/module/internal.h (0-day)
- Resolved style violations reported by scripts/checkpatch.pl
- Dropped patch 5 [6] so external patch [7] can be applied at
a later date post merge into module-next (Christophe Leroy)
