Timo Teräs	48dc80bbba	modutils: merge module_entry and module_info to common This merges the in-memory module info structures of modprobe and depmod.

Denys Vlasenko	1fd844267c	modprobe-small: if concurrent module load did not succeed, wait 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.

David Marchand	7d16964c3e	modinfo: fix module parsing with kernel >= 2.6.37 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:v00008086d00001560svsdbcsci\0 alias=pci:v00008086d0000154Asvsdbcsci\0 alias=pci:v00008086d00001557svsdbcsci\0 alias=pci:v00008086d0000154Fsvsdbcsci\0 alias=pci:v00008086d0000154Dsvsdbcsci\0 ... - Using modinfo -F alias ixgbe returns: alias: pci:v00008086d00001560svsdbcsci alias: pci:v00008086d00001557svsdbcsci* alias: pci:v00008086d0000154Dsvsdbcsci* ... 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).
