Revision 47f8f9297d2247d65ee46d8403a73b30f8d0249b authored by Pintu Kumar on 19 December 2014, 00:17:18 UTC, committed by Linus Torvalds on 19 December 2014, 03:08:10 UTC
This patch include CMA info (CMATotal, CMAFree) in /proc/meminfo. Currently, in a CMA enabled system, if somebody wants to know the total CMA size declared, there is no way to tell, other than the dmesg or /var/log/messages logs. With this patch we are showing the CMA info as part of meminfo, so that it can be determined at any point of time. This will be populated only when CMA is enabled. Below is the sample output from a ARM based device with RAM:512MB and CMA:16MB. MemTotal: 471172 kB MemFree: 111712 kB MemAvailable: 271172 kB . . . CmaTotal: 16384 kB CmaFree: 6144 kB This patch also fix below checkpatch errors that were found during these changes.
