2015-02-12modprobe-small: if concurrent module load did not succeed, waitDenys Vlasenko
usecase: two sd cards are being mounted in parallel at same time on dual core. example modules which are getting loaded is nls_cp437. While one module is being loaded , it makes state in /proc/modules as 'coming' and then starts doing its module init function (in our case - registering nls). meanwhile on other core, if modprobe returns that is has already been loaded, then it will continue and search for the nls list which is not yet finished from first module init. This fails resulting in not mounting sd card. function old new delta process_module 667 746 +79 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

This fixes a regression introduced with commit 78854520 (modprobe: revert checking for /, stop doing basename() on modprobe args, 2015-01-01) that broke modprobe options stored in /etc/modprobe.conf and /etc/modprobe.d/*.conf.

2014-07-04modinfo: fix module parsing with kernel >= 2.6.37David Marchand
display() function returns the length of the value we are displaying + 1. As a consequence, if we have field=value\0field=value\0field=value in the binary, then the second occurence will be skipped as ptr will miss the first character of the following field. Example trying to list aliases from ixgbe.ko on a 3.2 kernel. - In the module we have: alias=pci:v00008086d00001560sv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Asv*sd*bc*sc*i*\0 alias=pci:v00008086d00001557sv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Fsv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Dsv*sd*bc*sc*i*\0 ... - Using modinfo -F alias ixgbe returns: alias: pci:v00008086d00001560sv*sd*bc*sc*i* alias: pci:v00008086d00001557sv*sd*bc*sc*i* alias: pci:v00008086d0000154Dsv*sd*bc*sc*i* ... This problem appeared with kernel commit "modules: no need to align .modinfo strings" b6472776816af1ed52848c93d26e3edb3b17adab in 2.6.37. Fix this by not trusting display() return value but increment ptr by strlen(ptr) (the same way as depmod.c does).
